GENERAL DESCRIPTION

ZiLOG’s in-circuit emulators are interactive Windows-ori-

ented development tools providing a real-time environment

for developing and debugging software. Also included is a

full-featured macro cross assembler to enhance program-

mer productivity when used in conjunction with the Z89323

Emulator.

The Emulator provides a hardware platform that is a signif-

icant improvement compared to software simulators. The

Emulator is faster in operation, making it more practical

than software simulators for code development.

The Z89323 Emulator, which supports the Z89323 family

of DSP processors listed above, provides essential timing

and I/O circuitry to simplify user emulation of the prototype

hardware and software product.

The Z89323 Emulator can be connected to a serial port

(COM1, COM2, COM3, or COM4) of the host computer,

and it uses Graphical User Interface (GUI) software.

Notes:

1. Requires hand-wiring the Z89323 Emulator board to

your target board’s socket or by using a

daughterboard connected to JP2 and JP3.

2. Requires an optional, separately-purchased accessory

kit (Z8922300ZAC) from ZiLOG.

•

A Target Design

Typically, your design is a wire-wrapped or printed-cir-

cuit prototype that includes connectors which connect to

the emulator’s JP2 and JP3, or points which connect

with the emulator P6.

PRECAUTIONS

1. The Emulator cannot be operated while performing

ESD/EMI testing on the target board.

2. For 386 PCs, set the baud rate to 19.2K or less because

Windows’ communication driver does not guarantee

“reliable” operation at more than 9600 baud. Selecting

a high baud rate on some slower 386 machines may

crash the Windows environment.

3. Breakpoint overshoot. The Debug window shows the

processor halting at one or two instructions past the in-

struction where the breakpoint was set.

4. Do not start the Emulator with an OTP in the socket.

5. The GUI occasionally indicates

Executing

after a Halt

instruction. Pushing the GO button also indicates

Exe-

cuting

. (

Executing

displays at the top of the screen.)

LIMITATIONS

1. Switching Emulators without quitting the GUI is not

supported and causes unexpected results.

2. The Emulator breakpoint hardware does not distin-

guish between instruction and data fetches. Conse-

quently, the breakpoint hardware triggers when the

address specified matches either an instruction or data

fetch.

Example:

0000 LD A, #%0006

0002 ADD A, #%0002

0003 LD Y, @A

0004 NOP

0005 NOP

0006 JP %0000

0008 NOP

Setting the breakpoint at %0008 and click GO

causes the code to break at %0004 due to the data

fetch address match during the prior instruction.

This does not occur when Animate Mode is on

because the GUI is not using the hardware

breakpoints when in Animate Mode.

ROM PROTECT

option programming is temporarily

disabled.

4. The maximum loadable symbols is 32,768, provided

there is enough system resource (memory).

5. Although GUI 3.00 and later support baud rates up to

57.6K baud, the actual maximum usable rate may be

less due to limitations of the users hardware and/or

system software setup. The maximum usable rate is

determined by the users tolerance of the frequency of

communication errors.

6. The GUI does not recognize the PUSH and POP in-

structions when entered in the In-Line Assembler (De-

bug window). As a workaround, use

LD STACK,xxx

for PUSH and

LD xxx,STACK

for POP.
