Multitasks to use other Windows® applications while ZiLOG Developer
St udio (ZDS) is running
General Description
ZiLOG's in-circuit emulators are interactive, Windows-oriented development tools,
providing a real-time environment for emulation and debugging.
The Z86L98 emulator (Z86L9800ZEM) is a member of ZiLOG's ICEBOX® produ ct
family of in-circuit emulators. The emulator provides essential timing and I/O
circuitry to simplify user emulation of prototype hardware and software products.
The Z86L98 emulator provides users with a hardware platform to develop and
debug software in a real-time environment. In contrast, software simulators area
significantly slower making them less practical for code development.
The Z86L98 emulator can be connected to any serial port (COM1, COM2, COM3,
and COM4) on the host computer. ZiLOG Developer Studio (ZDS) software
initiates the interaction between the host computer and the emulator.
Notes/Limitations
The ROM/ROMLESS pin is used to configure the Z86D93ICE chip for either 32K
or 64K internal ROM. This configuratio n affects the Z86 L9800ZEM in the following
ways:
•
Does not support emulation of a ROMLESS operation
•
If the host software specifies that a device has between 4K to 32K of ROM,
the emulator operates as if it is emulating a device with 32K of ROM.
•
If the host software specifies that a device has more than 32K of ROM, the
emulator operates as if it is emulating a device with 64K of ROM.
Mask option pull-up resistance at 3V is approximately 200kΩ ±
50% at room temperature. Lower voltage can cause increased
resistance.

Precautions
ZDS IDE Limitations
1. Does not support downloading of PLC's .lod file
2. Overlapping contents of code/register/output windows when they dock
closely and horizontally.
Work around: Use View/Refresh command
3. Resizing windows sometimes changes the sta rting address back to zero and
the Data Memory window to its starting external address memory.
4. A new Debugger window sometimes hides behind open windows. Move or
reduce the number of open windows to view the new window.

5. There is no flag if th e debugger.ld file is older than the Assembly files when
connecting or downloading codes to the emulator.
6. External DATA memory fill takes at least 50 secs per 1K of data memory.
This slow-down avoids time-out e rrors and loss of co mmunication. Note that
using the External Data memory window is valid only when it exists on the
target application board.
7. Does not support saving debugger set-up/windows.
8. Does not support short cut or hot keys for the Debugger.
9. Does not support stepping into an include file.
10. The dissasembly window-up arrow scroll does not work yet.
Work around: Drag the vertical scroll bar.
Please refer to specific Customer Procurement Specifications
(CPS) or Product Information (PI) documents for specific
Limitations and Precautions for each ICEBOX®/Emulator.
All Z8 Emulators
1. Do not put a breakpoint at addresses after a STOP instruction. This causes
the program counter to continue at that location after Stop-Mode Recovery.
2. Single-stepping into a Halt instruction causes an ICEBOX® “Fatal Error”
message appear on the screen. The ICE chip must be reset, either by the
/Reset pin on the target board or by resetting the whole ICEBOX® by
pressing the emulator MASTER RESET button at the back of the emulator.
3. Clicking on the STOP button does not always halt the ICEBOX® execution.
If the application goes into Stop Mode or Halt Mode, the only way to halt the
emulator execution is by doing a Stop- Mode Recovery (as defined by the
user program). The application can also be reset by using the emulator
MASTER RESET button; however, this reset the whole ICEBOX®.
4. RC oscillator emulation is not supported.
5. When the software enters STOP mode and the STOP debugging button
control button is pressed, any SMR source on the application board is
activated, and the emulator jumps back to address 000C hex, which is
Note:
Z86L98 ZEM
Z8 In-Circuit Emulator
PS002602-1003
7
normal. But when continuing the program with a GO command from 000C
hex, a POR reset is performed, resetting all control registers.
6. The emulator cannot be operated while performing ESD/EMI testing on the
target board.
7. Ensure that the target cable is correctly aligned (pin1 to pin1) before
inserting it into the target system. Incorrect alignment can damage the
emulator/or the target system.
8. All Z8 control registers are Write-Only unless stated otherwise.
9. The general-purpose registers values after Power-On Reset or at the initial
emulator use are different than the actual device. The emulator self-test
always leaves the same values in the general -purpose registers, while the
real device has random or undefined values.
10. Power supply ramp-up/rise time must be set so that when the minimum
power-on reset time (Toper) expires, the VCC is in the specified operating
range of the device.
11. If the Program Counter jumps to an unknown address:
a. Stack is not set to internal. Register %F8(P01M Reg) bit D2 are not set
to State1.
b. The S tack Pointer Register %FE(SPH) and Reg ister %FF(SPL) are not
initialized. For the internal Stack, SPH does not have to be initialized
because it is not used. The SPH and SPL are reset to 00H after any
reset or Stop-Mode Recovery.
c. An instruction other than DI was used to disable interrupts.
d. The Stack overflowed into the general-purpose register locations.
e. When making changes to the IMR register, GLOBAL interrupts must
be disabled before using a DI instruction.
12. If the Program keeps resetting:
a. Program Counter rolled over from value FFFF to 0000 and proceeded
back to the beginning of program.
b. Watch-Dog Timer (WDT) was not refreshed from devices with the
WDT feature.
The emulator must not be started with an OTP device or
Adapter in the programming socket, because the emulator
might not start-up correctly.
Note

A shorted PLCC or DIP OTP can crash the emulator when
inserted into the OTP programming socket. If a PLCC part
is inserted and causes a temporary short, then the part
loses its functions. An attempt to perform BLANK CHECK
on such a part causes the hour-glass to appear
continuously. The Windows application must be reset and
restarted.
13. The bits of non-implemented features for devices having PC ON register
must be set to State1 on the emulator.
14. When interrupts are enabled, setting a breakpoint after a Halt instruction,
breaks the emulator at the first instructio n in the interrupt service routine that
is serviced when an IRQ occurs.
15. SCLK/16 Mode of SMR register is not supported.
16. The OTP activity bar is not proportionate to the address being processed.
Caution:
