Note: 1) These signals are required only for 16 bit accesses and not required when installed in 8 bit

system s. Devices should allow for 3-state signals not to consume current.

2) The signal should be grounded by the host.

3) The signal should be tied to VCC by the host.

4) The mode is required for CompactFlash Storage Cards.

5) The -CSEL signal is ignored by the card in PC Card modes. However, because it is not

pulled upon t he card in these modes, it should not be left floating by the host in PC Card

modes. In these modes, the pin should be connected by the host to PC Card A25 or

grounded by the host.

6) If DMA operations are not used, the signal should be held high or tied to VCC by the host. For

proper operation in older hosts: while DMA operations are not active, the card shall ignore

this signal,including a floating condition

7) Signal usage in True IDE Mode except when Ultra DMA mode protocol is active.

8) Signal usage in True IDE Mode when Ultra DMA mode protocol DMA Write is active.

9) Signal usag e in True IDE Mode when Ul tra DMA mode protocol DMA Read is active.

10) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Write is active.

11) Signal usage in PC Card I/O and Memory Mode when Ultra DMA mode protocol DMA Read is active.

12) Signal usage in PC Card I/O and Memory Mode when Ultra DMA protocol is active.

whether a byte or a word operation is being performed. -CE2 always accesses

the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the

word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1,

-CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29,

Table 31, Table 35, Table 36 and Table 37.

This signal is the same as the PC Card Memory Mode signal.

In the True IDE Mode, -CS0 is the address range select for the task file

registers while -CS1 is used to select the Alternate Status Register and the

Device Control Register.

Input Acknowledge

DMARQ

(True IDE Mode)

O 43 This signal is not used in this mode.

The Input Acknowledge signal is asserted by the CompactFlash Storage Card

when the card is selected and respondin g to an I/O read cycle at the address th at

is on the address bus. This signal is u sed by the host to control the enable of any

input data buffers between the CompactFlash Storage Card and the CPU.

This signal is a DMA Request that is used for DMA data transfers between host

and device. It shall be asse rted by the device when it is ready to transfer data to

or from the host. For Multiword DMA transfers, the direction of data transfer is

controlled by -IORD and -IOWR. This signal is used in a hand shake manner with

-DMACK, i.e., the device shall wait until the host asserts -DMACK before

negating DMARQ, and reasserting DMARQ if there is more data to transfer.

DMARQ shall not be driven when the device is not selected.

While a DMA operation is in progress, -CS0 and –C S1 shall be held negated and

the width of the transfers shall be 16 bits.

If there is no h ardware support for DMA mode in the host, this outpu t signal is not

used and should no t be connected at the host. In this case , the BIOS must report

that DMA mode is not supported by the host so that device drivers will not

attempt DMA mode.

A host that does not support DMA mode and implements both PCMCIA and

True-IDE modes of operation need not alter the PCMCIA mode connections

while in True-IDE mode as long a s this does n ot prevent proper operation in any

mode.

I 34 This signal is not used in this mode.

This is an I/O Read strobe generate d by the host. This signal g ates I/O data onto

the bus from the CompactFla sh Storage Card when th e card is configured to use

the I/O interface.

In True IDE Mode, while Ultra DMA mode is not active, this signal has the same

function as in PC Card I/O Mode.

In True IDE Mode when Ultra DMA mode DMA Read is active, this signal is

asserted by the host to indicate that th e host is read to receive Ultra DMA data-in

bursts. The host may negate -HDMARDY to pause an Ultra DMA transfer.

In True IDE Mode when Ultra DMA mode DMA Write is active, this signal is the

data out strobe generated by the host. Both the rising and falling edge of

HSTROBE cause data to be latched by the device. The host may stop

generating HSTROBE edges to pause an Ultra DMA data-out burst.

I 35 This signal is not used in this mode.

The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into th e

CompactFlash Storage Card controller registers when the CompactFlash

Storage Card is configured to use the I/O interface.

The clocking shall occur on the negative to positive edge of t he signal ( tr a iling

edge).

In True IDE Mode, while Ultra DMA mode protocol is not active, this signal has

the same function as in PC Card I/O Mode. When Ultra DMA mode protocol is

supported, this signal must be negated before entering Ultra DMA mode

protocol.

In True IDE Mode, while Ultra DMA mode protocol is active, the a ssertio n of this

signal causes the termination of the Ultra DMA burst.

-OE

(PC Card Memory Mode)

-OE

(PC Card I/O Mode)

-ATA SEL

(True IDE Mode)

I 9 This is an Output Enable strobe generated by the host interface. It is used to read

data from the CompactFlash Stora ge Card in Memory Mode and to read the CIS

and configuration registers.

In PC Card I/O Mode, this signal is used to read the CIS and configuration

registers.

To enable True IDE Mode this input should be grounded by the host.

READY

(PC Card Memory Mode)

-IREQ

(PC Card I/O Mode)

INTRQ

(True IDE Mode)

O 37 In Memory Mode, this signal is set hig h when the CompactFlash Storage Card is

ready to accept a new data transfer operation and is held low when the card is

busy.

At power up and at Reset, the READY signal is held low (busy) until the

CompactFlash Storage Card has completed its power up or reset function. No

access of any type should be made to the CompactFlash Storage Card during

this time.

Note, however, that when a card is powered up and used with RESET

continuously disconnected or asserted, the Reset function of the RESET pin is

disabled. Conse quently, the contin uous assertion of RESET from the application

of power shall not cause the READY signal to remain continuously in the busy

state.

I/O Operation – After the CompactFlash Storage Card Card ha s been configured

for I/O operation, this signal is used as -Interrupt Request. This line is strobed

low to generate a pulse mode interrupt or held low for a level mode interrupt.

In True IDE Mode signal is the active high Interrupt Request to the host.

Attribute Memory Select

-REG

(PC Card I/O Mode)

I 44 This signal is used during Memory Cycles to distinguish between Common

Memory and Register (Attribute) Memory accesses. High for Common Memory,

Low for Attribute Memory.

The signal shall also be active (low) du ring I/O Cycles when the I/O address is on

the Bus.

-DMACK

(True IDE Mode) This is a DMA Acknowledge signal that is asserted by the host in response to

DMARQ to initiate DMA transfers.

While DMA operations are not active, the card shall ignore the -DMACK signal,

including a floating condition.

If DMA operation is not supported by a True IDE Mode only host, this signal

should be driven high or connected to VCC by the host.

A host that does not support DMA mode and implements both PCMCIA and

True-IDE modes of operation need not alter the PCMCIA mode connections

while in True-IDE mode as long as this does not prevent proper operation all

modes.

RESET

(PC Card Memory Mode)

RESET

(PC Card I/O Mode)

-RESET

(True IDE Mode)

I 41 The CompactFlash Storage Card is Reset when the RESET pin is high with the

following important exception:

The host may leave the RESET pin open or keep it continually high from the

application of power without causing a continuous Reset of the card. Under

either of these conditions, the card shall emerge from power-up having

completed an initial Reset.

The CompactFlash Storage Card is also Reset when the Soft Reset bit in the

Card Configuration Option Register is set.

This signal is the same as the PC Card Memory Mode signal.

In the True IDE Mode, this input pin is the active low hardware reset from the

host.

This signal is the same as the PC Card Memory Mode signal.

In True IDE Mode, except in Ultra DMA modes, this outp ut signal may be used as

IORDY.

In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is

asserted by the host to indicate that the device is read to receive Ultra DMA

data-in bursts. The device may negate -DDMARDY to pause an Ultra DMA

transfer.

In True IDE Mode, when Ultra DMA mode DMA Write is active, this signal is the

data out strobe generated by the device. Both the rising and falling edge of

DSTROBE cause data to be latched by the host. The device may stop

10 while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (50 pF with

DC current 700 μA low state and 150 μA high state per socket).

2) Resistor is optional.

3) Status Signals: the socket shall present a loa d to the card no larger than 50 pF 10 at a DC current of 400 μA low

state and 100 μA high state, in cluding pull-up re sistor. The card shall be ab le to drive a t least the following load

10 while meeting all AC timing re quire ments: 5 0 pF at a DC current of 4 00 μA low state a nd 100 μA h i gh state.

5) Status Signals: the socket shall presen t a load to the card no larger than 50 pF 10 at a DC current of 40 0 μA low

state and 100 μA high state, in cluding pull-up re sistor. The card shall be ab le to drive at leas t the following lo ad

10 while meeting all AC timing requirements: 50 pF at a DC current o f 400 μA low state and 1100 μA high state.

6) BVD2 was not defined in the JEIDA 3.0 release. Systems fully supporting JEIDA release 3 SRAM cards shall

pull-up pin 45 (BVD2) to avoid sensing their batteries as “Low.”

7) Address Signals : each card shall present a load of no more than 100pF 10 at a DC current of 450μA low state and

150μA high state. The host shall be able to drive at least the following load 10 while meeting all AC tim ing

requirements: (the number of sockets wired in parallel) multiplied by (100pF with DC current 450 μA low st ate

and 150μA high state per socket).

8) Data Signals: the host and each card shall present a load no larger than 50pF 10 at a DC current of 450μA and

150μA high state. The host and each card sh all be able to drive at least the following load 10 while meeting all AC

timing requirements: 100 pF with DC current 1.6mA low state and 300μA hi gh state. This permits the host to wire

two sockets in parallel without derating the card access speeds.

9) Reset Signal: This signal is pulled up to pre vent the input from floating when a CFA to PCMCIA adapter is used in

a PCMCIA revision 1 host. However, to minimize DC current drain through the pull-up resistor in normal

operation the pull-up should be turned off once the Reset signal has been actively driven low by the host.

Consequently, the input is specified as an I2Z because the resistor is not necessarily detectable in the input

current leakage test.

10) Host and card restrictions for CF Advanced Timing Modes and Ultra DMA modes: Additional Requirements for

CF Advanced Timing Modes and Ultra DMA Electrical Requirements for additional required limitations on the

implementation of CF Advanced Timing modes and Ultra DMA modes respectively.

 Additi onal Requirements for CF Advanced Timing Modes

The CF Advanced Timing modes include PCMCIA I/O and Memory modes that are 100ns or faster and True

IDE PIO Modes 5,6 and Multiword DMA Modes 3,4.

When operating in CF Advanced timing modes, the host shall conform to the following requirements:

1) Only one CF device shall be attached to the CF Bus.

2) The host shall not present a load of more than 40pF to the device for all signals, including any cabling.

3) The maximum cable length is 0.1 5 m (6 in). The cable length is measured from the card co nnector to the host

controller. 0.46 m (18 in) cables are not supported.

4) The -WAIT and IORDY signals shall be ignored by the host.

Devices supporting CF Advanced timing modes shall also support slower timing modes, to ensure operability with

systems that do not support CF Advanced timing modes

Notes: 1) The paramete rs tUI, tMLI : (Ultra DMA Data-In Burst Device T ermination Timing and Ultra DMA

Data-In Burst Host Termination Timing), and tLI indicate sender-to-recipient or recipient-to-sender

interlocks, i.e., one agent (eithe r sender or recipient) is waiting for the other agen t to respond with a

signal before proceeding. tUI is an unlimited interlock that has no maximum time value. tMLI is a

limited time-out that has a defined minimum. tLI is a limited time-out that has a defined maximum.

2) 80-conduc tor cabling shall be required in orde r to meet setup (t DS, tCS) and hold (tDH, tCH) times

in modes greater than 2.

3) Timing for tDVS, tDVH, tCVS and tCVH shall be met for lumped capacitive loads of 15 and 40 pF

at the connector where the Data an d STROBE signa l s have the same capa citive load value. Due to

reflections on the cable, these timing measurements are not valid in a normally functioning system.

4)For all modes the pa rameter tZIORDY may b e greater than tENV due t o the fact that the host h as a

pull-up on IORDY- giving it a known state when released.

5)The parameters tDS, and tDH for mode 5 are defined for a recipient at the end of the cable only in

a configuration with a single device located at the end of the cable. This could result in the minimum

values for tDS and tDH for mode 5 at the middle connector being 3.0 and 3.9 ns respectively.

Notes: 1) All timing measurement switching points(low to high and high to low) shall be taken at 1.5 V.

2) The correct data value shall be captured by the recipient given input data with a slew rate of 0.4

V/ns rising and falling and th e input STROBE with a slew rate of 0 .4 V/ns rising and falling a t tDSIC

and tDHIC timing (as measured through 1.5 V).

3) The parameters tDVSIC and tDVHIC shall be met for lumped capacitive loads of 15 and 40 pF at

the IC where all signals have the same capacitive load value. Noise that may couple onto the output

signals from external sources has not been included in these values.

133X CompactFlash Card

Note: 1) The sender shall be tested while driving an 18 inch lon g, 80 conductor cable with PVC insulation

material. The signal under te st shall be cut at a test point so that it has not trace, cab le or recipient

loading after the test point. All other signals should remain connected through to the recipient. The

test point may be located at an y point between the sender’s series termination re sistor and one half

inch or less of conductor exiting the connector. If the test point is on a cable conductor rather than the

Card Configuration

The CompactFlash Storage Cards is identified by appropriate information in the Card Information Structure

(CIS). The following configuration registers are used to coordinate the I/O spaces and the Interrupt level of cards

that are located in the system. In addition, these registers provide a method for accessing status information

about the CompactFlash Storage Car d that may be used to ar bitrate be tween multiple inte rr upt sources on the

same interrup t le vel or to re pla ce status info rma tion tha t appe ars on dedicated pins in memor y cards th at ha ve

alternate use in I/O cards.

I/O Transfer Function

The I/O transfer to or from the CompactFlash Storage can be either 8 or 16 bits. When a 16 bit accessible

port is addressed, the signal -IOIS16 is asserted by the CompactFlash Storage. Otherwise, the -IOIS16

signal is de-asserted. When a 16 bit transfer is attempted, and the -IOIS16 signal is not asserted by the

CompactFlash Storage, the system shall generate a pair of 8 bit references to access the word‘s even byte

and odd byte. The CompactFlash Storage Card permits both 8 and 16 bit accesses to all of its I/O addresses,

so -IOIS16 is asserted for all addr esses to which the CompactFlash Storage responds. The CompactFlash

Storage Card may request the host to extend the length of an input cycle until data is ready by asserting the

-WAIT signal at the start of the cycle.

True IDE Mode I/O Transfer Function

The CompactFlash Storage Card can be configured in a True IDE Mode of operation. The CompactFlash Storage

Card is configured in this mode only when the - OE input signal is grounded by the host during the power off to

power on cycle. Optionally, CompactFlash Storage Cards may support the following optional detection methods:

1. The card is permitted to monitor the – OE (-ATA SEL) signa l at any time(s) and switch to PCMCIA mode u pon

detecting a high level on the pin.

2. The card is permitted to re-arbitrate the interface mode determination following a transition of the (-)RESET pin.

3. The card is permitte d to mon ito r the –OE (-ATA SEL) signal at any time(s) and switch to True IDE mo de u pon

CF-ATA Drive Register Set Definition and Protocol

The CompactFlash Storage Card can be configured as a high performance I/O device through:

a) The standard PC -A T dis k I/O ad dress spaces 1F0h-1F7 h, 3F6h-3F7h (prima ry ) or 170h- 17 7h , 376h -377 h

(secondary) with IRQ 14 (or other available IRQ).

b) Any system decoded 16 byte I/O block using any available IRQ.

c) Memory space.

The communication to or from the CompactFlash Storage Card is done using the Task File registers, which

provide all the necessary registers for control and status information related to the storage medium. The PCMCIA

interface connects peripherals to the host using four register mapping methods. Table 39 is a detailed description

of these methods:

 CF-ATA Registers

The following section describes the hardware registers used by the host software to issue commands to the

CompactFlash device. These registers are often collectively referred to as the “task file.”

¾ Data Register (Address - 1F0h[170h];Offset 0,8,9)

The Data Register is a 16 bit register, and it is used to transfer data blocks between the CompactFlash

Storage Card data buffer and the Host. This register overlaps the Error Register.

Error Register (Address - 1F1h[171h]; Offset 1, 0Dh Read Only)

This register contains additional information about the source of an error when an error is indicated in bit 0

of the Status register.

This register is also accessed in PC Card Modes on data bits D15-D8 during a read operation to offset 0

with -CE2 low and -CE1 high.

Bit 7 (BBK/ICRC): this bit is set when a Bad Block is detected. This bit is also set when an interface CRC

error is detected in True IDE Ultra DMA modes of operation.

Bit 6 (UNC): this bit is set when an Uncorrectable Error is encountered.

Bit 5: this bit is 0.

Bit 4 (IDNF): the requested sector ID is in error or cannot be found.

Bit 3: this bit is 0.

Bit 2 (Abort) This bit is set if the comman d has been a borted because of a CompactFlash Storag e Card

status condition: (Not Ready, Write Fault, etc.) or when an invalid command has been issued.

Bit 1 This bit is 0.

Bit 0 (AMNF) This bit is set in case of a general error.

133X CompactFlash Card

Transcend Information Inc.

¾ Feature Register (Address - 1F1h[171h]; Offset 1, 0Dh Write Only)

This register provides information regarding features of the CompactFlash Storage Card that the host can

utilize. This register is also accessed in PC Card modes on data bits D15-D8 during a write operation to

Offset 0 with -CE2 low and -CE1 high.

¾ Sector Count Register (Address - 1F2h[172h]; Offset 2)

This register contains the numbers of sectors of data requested to be transferred on a read or write

operation between the host and the CompactFlash Storage Card. If the value in this register is zero, a count

of 256 sectors is specified. If the command was successful, this register is zero at command completion. If

not successfully completed, the register contains the number of sectors that need to be transferred in order

to complete the request.

¾ Sector Number (LBA 7-0) Register (Address - 1F3h[173h]; Offset 3)

This register contains the starting sector number or bits 7-0 of the Logical Block Address (LBA) for any

CompactFlash Storage Card data access for the subsequent command.

¾ 6.1.5.5 Cylinder Low (LBA 15-8) Register (Address - 1F4h[174h]; Offset 4)

This register contains the low order 8 bits of the starting cylinder address or bits 15-8 of th e Logical Block

Address.

¾ Cylinder High (LBA 23-16) Register (Address - 1F5h[175h]; Offset 5)

This register contains the high order bits of the starting cylinder add ress or bits 23-16 of th e Logical Block

Address.

¾ Drive/Head (LBA 27-24) Register (Address 1F6h[176h]; Offset 6)

The Drive/Head register is used to select the drive and head. It is also used to select LBA addressing

instead of cylinder/head/sector addressing.

Bit 7: this bit is specified as 1 for backward compatibility reasons. It is intended that this bit will become

obsolete in a future revision of the specification. This bit is ignored by some controllers in some

commands.

Bit 6: LBA is a flag to select either Cylinder/Head/Sector (CHS) or Logical Block Address Mode (LBA).

When LBA=0, Cylinder/Head/Sector mode is selected. When LBA=1, Logical Block Address is

selected. In Logical Block Mode, the Logical Block Address is interpreted as follows:

LBA7-LBA0: Sector Number Register D7-D0.

LBA15-LBA8: Cylinder Low Register D7-D0.

LBA23-LBA16: Cylinder High Register D7-D0.

LBA27-LBA24: Drive/Head Register bits HS3-HS0.

Bit 5: this bit is specified as 1 for backward compatibility reasons. It is intended that this bit will become

obsolete in a future revisions of the specification. This bit is ignored by some controllers in some

commands.

Bit 4 (DRV): DRV is the drive number. When DRV=0, drive (card) 0 is selected. When DRV=1, drive (card)

1 is selected. Setting this bit to 1 is obsolete in PCMCIA modes of operation. If the obsolete

functionality is support by a C F Storage Card , the CompactF lash Storage C ard is set to be Card 0 or 1

using the copy field (Drive #) of the PCMCIA Socket & Copy configuration register.

133X CompactFlash Card

Transcend Information Inc.

Bit 3 (HS3): when operating in th e Cylinde r, Head , Sector mode, this is b it 3 o f the h ea d nu mber. It is Bit

27 in the Logical Block Address mode.

Bit 2 (HS2): when operating in th e Cylinde r, Head, Sector mode, this is bit 2 o f the h ead number. It is Bit

26 in the Logical Block Address mode.

Bit 1 (HS1): when operating in th e Cylinde r, Head, Sector mode, this is bit 1 o f the h ead number. It is Bit

25 in the Logical Block Address mode.

Bit 0 (HS0): when operating in th e Cylinde r, Head, Sector mode, this is bit 0 o f the h ead number. It is Bit

24 in the Logical Block Address mode.

¾ Status & Alternate Status Registers (Address 1F7h[177h]& 3F6h[376h]; Offsets 7 & Eh)

These registers return the CompactFlash Storage Card status when read by the host. Reading

the Status register does clear a pending interrupt w hile reading the Auxiliary Status register does

not. The status bits are described as follows:

Bit 7 (BUSY): the busy bit is s et when the CompactFlash Storage Card has access to the command buffer

and registers and the host is locked out from accessing the command register and buffer. No other bits

in this register are valid when this bit is set to a 1. During the data transfer of DMA commands, the Card

shall not assert DMARQ unless either the BUSY bit, the DRQ bit, or both are set to one.

Bit 6 (RDY): RDY indicates whether the device is capable of performing CompactFlash Storage Card

operations. This bit is cleared at power up and remains cleared until th e Comp actFlash Stor ag e Card

is ready to accept a command.

Bit 5 (DWF): This bit, if set, indicates a write fault has occurred.

Bit 4 (DSC): This bit is set when the CompactF lash Storag e Card is ready.

Bit 3 (DRQ): The Data Request is set when the CompactFlash Storage Card requires that information be

transferred either to or from the host through the Data register. During the data transfer of DMA

commands, the Card shall not assert DMARQ unless either the BUSY bit, the DRQ bit, or both are set

to one.

Bit 2 (CORR): This bit is set when a Correctable data error has been encountered and the data has been

corrected. This condition does not terminate a multi-sector read operation.

Bit 1 (IDX): This bit is always set to 0.

Bit 0 (ERR): This bit is set when the previou s command has ende d in some type of err or. The bits in the

Error register contain additional information describing the error. It is recommended that media access

commands (such as Read Sectors and Write Sectors) that end with an error condition should have the

address of the first sector in error in the command block registers.

133X CompactFlash Card

Transcend Information Inc.

¾ Device Control Register (Address - 3F6h[376h]; Offset Eh)

This register is used to control the CompactFlash Storage Card inter r u pt req ue st and to issue an ATA soft

reset to the card. This register can be written even if the device is BUSY. The bits are defined as follows:

Bit 7: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0.

Bit 6: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0.

Bit 5: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0.

Bit 4: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0.

Bit 3: this bit is ignored by the CompactFlash Storage Card. The host software should set this bit to 0.

Bit 2 (SW R st): t his bit is s et to 1 i n orde r to f orce the CompactFlas h S t orag e C ard to pe rf orm an AT D i sk

controller Soft Reset operation. This does not change the PCMCIA Card Configuration Registers as a

hardware Reset does. The Card remains in Reset until this bit is reset to ‘0.’

Bit 1 (-IEn): the Interrupt Enable bit enables interrupts when the bit is 0. When the bit is 1, interrupts from

the CompactFlash Storage Card are disabled. This bit also controls the Int bit in the Configuration and

Status Register. This bit is set to 0 at power on and Reset.

Bit 0: this bit is ignored by the CompactFlash Storage Card.

¾ Card (Drive) Address Register (Address 3F7h[377h]; Offset Fh)

This register is provided for compatibility with the AT disk drive interface. It is recommended that this

Bit 7: this bit is unknown.

Implementation Note:

Conflicts may occur on the host data bus when this bit is provided by a Floppy Disk Controller

operating at th e same addre sses as the CompactFlash Stor age Card. Fo llowing are som e possible

solutions to this problem for the PCMCIA implementat ion:

1) Locate the CompactFlash Storage Card at a non-conflicting address, i.e. Secondary address

(377) or in an independently decoded Address Space when a Floppy Disk Controller is located at

the Primary addresses.

2) Do not install a Floppy and a CompactFlash Storage Card in the system at the same time.

3) Implement a socket adapter that ca n be programmed to (conditionally ) tri-state D7 of I/0 address

3F7h/377 h when a CompactFlash Stora ge Card is installed and con versely to tristate D6-D0 of

I/O address 3F7h/377h when a floppy controller is installed.

4) Do not use the CompactFlash Storage Card’s Drive Address register. This may be accomplished

by either a) If p ossible, progra m the host adapt er to enable only I /O addresses 1F0h-1F7h, 3F 6h

(or 170h-177h, 176h) to the CompactFlash Storage Card or b) if provided use an additional

Primary / Secondary configuration in the CompactFlash Storage Card which does not respond to

accesses to I/O locations 3F7h and 377h. With either of these implementations, the host

software shall not attempt to use information in the Drive Address Register.

Bit 6 (-WTG): this bit is 0 when a write operation is in progress; otherwise, it is 1.

Bit 5 (-HS3): this bit is the negation of bit 3 in the Drive/Head register.

Bit 4 (-HS2): this bit is the negation of bit 2 in the Drive/Head register.

Bit 3 (-HS1): this bit is the negation of bit 1 in the Drive/Head register.

Bit 2 (-HS0): this bit is the negation of bit 0 in the Drive/Head register.

Bit 1 (-nDS1): this bit is 0 when drive 1 is active and selected.

Bit 0 (-nDS0): this bit is 0 when the drive 0 is active and selected.

 Check Power Mode - 98h or E5h

If the CompactFlash Storage Card is in, going to, or recovering from the sleep mode, the Compact Flash Storage

Card sets BSY, sets the Sector Count Register to 00h, clears BSY and generates an interrupt.

If the CompactFlash Storage Card is in Idle mode, the CompactFlash Storage Card sets BSY, sets the Sector

Count Register to FFh, clears BSY and generates an interrupt.

133X CompactFlash Card

 Execute Drive Diagnostic - 90h

When the diagnostic command is issued in a PCMCIA configuration mode, this command runs only on the

CompactFlash Storage Card that is addressed by the Drive/Head register. This is because PCMCIA card

interface does not allows for direct inter-drive communication (such as the ATA PDIAG and DASP signals). When

the diagnostic command is issued in the True IDE Mode, the Drive bit is ignored a nd the diag nostic comman d is

executed by both the Master and the Slave with the Master responding with status for both devices.

Diagnostic Codes are returned in the Error Register at the end of the command.

 Erase Sector(s) - C0h

This command is used to pre-erase and condition data sectors in advance of a Write without Erase or Write

Multiple without Erase command. Ther e is no da ta transfer associated with this command but a Write Fault err or

status can occur.

133X CompactFlash Card

Transcend Information Inc.

 Flush Cache – E7h

This command causes the card to complete writing data from its cache. The card returns status with RDY=1 and

DSC=1 after the data in the write c ache buffer is written to the media. If the Compact Flash Storage Card does not

support the Flush Cache command, the Compact Flash Storage Card shall return command aborted.

 Format Track - 50h

This command writes the desired head and cylinder of the selected drive with a vendor unique data pattern

(typically FFh or 00h). To rem ain host backward compatible, the CompactFlash Storage Card expects a sector

buffer of data from the host to follow the command with the same protocol as the Write Sector(s) command

although the information in the buffer is not used by the CompactFlash Storage Card. If LBA=1 then the number of

sectors to format is taken from the Sec Cnt register (0=256). The use of this command is not recommended.
