Zilog's in-circuit emulators are interactive, Windoworiented development tools, providing a real-time environment for emulation and debugging. The emulator provides essential timing and I/O circuitry to simplify user emulation of the prototype hardware and software product. Data entering,and program debugging, are performed by the monitor ROM and the host package, which communicates through RS-232C serial interface. The user program can be downloaded directly from the host computer through the RS-232C connector. User code may be executed through debugging commands in the monitor. The Z86C6200ZEM emulator can be connected to a serial port (COM1, COM2, COM3, and COM4) of the host computer and uses Graphical User Interface (GUI) software.

Breakpointing in interrupt service routine and singlestepping pass the IRET statement will cause global interrupts to be disabled. 2. Do not put breakpoint at address after Stop instruction. This will cause program counter to continue at that location after a Stop-Mode Recovery.

The ICEBOX cannot stop timers during single-step operation, or upon reaching of breakpoint. 5. Changing drives in file download and load symbol dialog boxes is not anticipated by the GUI. Typing in the filename in a directory other than shown in “Path:” will result in “File not found”. Changing the drive using the mouse is the workaround. 6. The initial blue Zilog screen will be distorted by other active windows. This only affects the appearance, not functionality, of the GUI. 7. Switching ICEBOXes without quitting the GUI is not supported. 8. The maximum symbols that can be loaded is 32768, provided that there is enough system resource (memory). Z86C6200ZEM 9. The ICEBOX breakpoint hardware does not distinguish between instruction and data fetches. When a breakpoint in the GUI is set, the breakpoint hardware triggers when the addresses match for either code or data fetches. Example: 000C 000E 0010 0012 0013 0016 SRP LD LD NOP JP NOP #%0 R4, #%0016 R5, @R4 3. The ICEBOX cannot stop Timers and Interrupts at a breakpoint or during ICEBOX Halt operation or a single-step operation. The stack will overflow if an interrupt is enabled and the ICEBOX is in HALT, singlestep, or breakpoint. (This is a limitation of the ICE chip.) 4. Check the TPOR and T WDT specifications of the device that you wish to emulate. The actual specification may differ from the ICE chip specifications. Setting the breakpoint at %0016 and click GO. 5. The general-purpose registers after Power-On Reset or at initial emulator use will be different than the actual device. The emulator self test will always leave the same values in the general-purpose registers, while the real device will have a random/undefined value in the general-purpose registers. Result: The code will break and stop at %0012. 6. RC oscillator emulation is not supported. Note: This will not happen when Animate Mode is on because the GUI is not using the hardware breakpoints when in Animate Mode. 7. GUI software versions prior to 3.00 are incompatible with hardware containing BOOTROM 3.00. The GUI software may still boot, but will fail at some later point of the session. %000C 10. If the emulator is running a user code at full speed and the port window is opened: Switching to another application or minimizing the GUI (then restoring) will result in the following ICEBOX Communications Error message: “Emulator rejected command: target program is executing.” This message may need to be cleared several times (as many as seven) before the GUI returns to normal operation. Workaround: Always close the port window before leaving the GUI. PRECAUTION LIST All Devices 1. All Z8 control registers are write only unless stated otherwise. 2. Power Supply ramp-up/rise time must be such that when minimum power-on reset time (TPOR) expires, then the VCC must be in the supported specified operating range of the device. 8. When device serialization is enabled in the OTP dialog, the GUI copies the current serial number to code memory immediately before performing a VERIFY operation. If this behavior is undesirable, then device serialization must be disabled prior to invoking the VERIFY operation. 9. The status color bar in OTP dialog box will be cleared in the area where a new window opens on top of it. 10. 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. 11. Do not press hardware reset when the ICEBOX is in OTP programming. If reset is pressed while the GUI is doing OTP programming, close the OTP dialog window and reopen it to reload the information back to the hardware. Note: Although the Command Status shows “Processing” after the GUI reestablishes the communication link when Retry was selected, the ICEBOX is actually sitting idle.) 67 Z86C6200ZEM 68
