Z86L98 ZEM Z8 In-Circuit Emulator 2
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 product 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 configuration affects the Z86L9800ZEM 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 200k 50% at room temperature. Lower voltage can cause increased resistance.

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

There is no flag if the debugger.ld file is older than the Assembly files when connecting or downloading codes to the emulator. External DATA memory fill takes at least 50 secs per 1K of data memory. This slow-down avoids time-out errors and loss of communication. Note that using the External Data memory window is valid only when it exists on the target application board. Does not support saving debugger set-up/windows. Does not support short cut or hot keys for the Debugger. Does not support stepping into an include file. The dissasembly window-up arrow scroll does not work yet. Work around: Drag the vertical scroll bar.

Note: 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. 2. 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. Single-stepping into a Halt instruction causes an ICEBOX OFatal ErrorO 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. 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. RC oscillator emulation is not supported. 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

normal. But when continuing the program with a GO command from 000C hex, a POR reset is performed, resetting all control registers. 6. 7. The emulator cannot be operated while performing ESD/EMI testing on the target board. 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. All Z8 control registers are Write-Only unless stated otherwise. 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. 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. If the Program Counter jumps to an unknown address: a. b. Stack is not set to internal. Register %F8(P01M Reg) bit D2 are not set to State1. The Stack Pointer Register %FE(SPH) and Register %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. An instruction other than DI was used to disable interrupts. The Stack overflowed into the general-purpose register locations. When making changes to the IMR register, GLOBAL interrupts must be disabled before using a DI instruction.

If the Program keeps resetting: a. b. Program Counter rolled over from value FFFF to 0000 and proceeded back to the beginning of program. Watch-Dog Timer (WDT) was not refreshed from devices with the WDT feature.
Note: The emulator must not be started with an OTP device or Adapter in the programming socket, because the emulator might not start-up correctly.

Caution:
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. 14.
The bits of non-implemented features for devices having PC ON register must be set to State1 on the emulator. When interrupts are enabled, setting a breakpoint after a Halt instruction, breaks the emulator at the first instruction in the interrupt service routine that is serviced when an IRQ occurs. SCLK/16 Mode of SMR register is not supported. The OTP activity bar is not proportionate to the address being processed.
