6. This issue is due to an inherent design limitation which affects both the Z8EOOX and the emulator WDT in HALT mode The Z8M001 ICEchip has a bug that causes the watchdog timer to continue to run in HALT mode even if the WDT in HALT bit TCTLHI 7 is cleared Work around this bug by emulating the code with the WDT stopped and then enabling the watchdog just before programming an OTP device The Z8E00X devices are not affected by this problem It is an emulation only limitation The RC OSCILLATOR option bit is not available for the Z8E000 and Z8E001 devices Select the EPROM PROTECT TEST MODE KILL option bit only after programming the device and verifying the code From that point select the EPROM PROTECT option and program again Finally run VERIFY one last time this run should FAIL to ensure that the code is truly protected The ZDS command VECTOR RESET adds a jump at address 20h This command prevents the user from writing to the TCTLHI register to configure the WDT This command should not be used for Z8Plus parts The WDT and SMR functions of the emulator are tailored to match Z8PEOOX devices These functions do not perform exactly the same as for Z8E00X devices Specifically the SMR is edge triggered not level triggered On Z8EOOX devices operation does not resume until the pin is released The WDT of the emulator like the Z8PEOOX devices themselves counts up not down as on Z8E00X devices DS008801 Z8X1299 ZiLOG
7. mand Status indicates PROCESSING after the GUI reestablishes the communication link when Retry is selected in the Out of Synchronization with the Emulator dialog box When device serialization is enabled in the OTP dialog ZDS copies the current serial number to code memory immediately before performing a VERIFY operation If this software action is undesirable then device serialization should be disabled prior to invoking the VERIFY operation When interrupts are enabled breakpointing after a HALT instruction the emulator breaks at the first instruction in the interrupt service routine that is serviced when an interrupt occurs The RESET default state of the emulator differs from the parts Particularly the TCTLHI register is reset differently than the device Set this register to the desired value as the first instruction in the program The emulator does not execute the first instruction to load the TCTLHI register if the user presses RESET and then GO from ZDS or the GUI For the first instruction to execute correctly the user should press the RESET GO button Z8ICE001ZEM Z8Plus Emulator LIMITATIONS 1 3 Although GUI 3 00 and later support baud rates up to 57 6 K baud the actual maximum usable rate may be less due to limitations of the user s hardware or systems software setup The maximum usable rate is determined by the user s tolerance of the frequency of communication errors Clicking on the HALT button d
