  • Page 19: Emulation Operation

    C84 ICEBOX ANUAL EMULATOR OPERATION Resetting ™ Pressing the RESET button on the ICEBOX resets the state of the target Z8 and much of the status that you establish using the GUI. For example, it resets the emulated ROM size to 4 KB, and clears all 32 KB Breakpoint ROM.

  • Page 20: Led Operation

    Special Emulator Operation Considerations The C84 ICEBOX uses the Z86C50 ICE Chip; therefore, emulation at more than 12 MHz requires that the Expanded Register file timing of the ICE Chip be slowed down to SCLK x 2. This is accomplished by loading value %01 to ICECON Register (BankF, Register A) of the ICE Chip.
