PRECAUTIONS
All Devices
1. This emulator is only supported by ZDS version 2.12
or later.
2. The emulator cannot be operated while performing
ESD/EMI testing on the target board.
3. Ensure that the target cable is correctly aligned (pin 1
to pin 1) before inserting into the target system.
Incorrect alignment may damage the emulator and/or
the target system.
4. If the Program Counter jumps to an unknown address:
a. The Stack may have overflowed into the general-
purpose register locations, and/or
b. An extra POP, PUSH, IRET, or RET was
encountered.
5. If the Program keeps resetting:
a. The Program Counter rolled over from value end
address to value 0000 and proceeded back to the
beginning of the program.
b. The Watch-Dog Timer (WDT) was not refreshed
from devices with the WDT feature.
6. Check the T_POR and T_WDT specifications of the device
required for emulation. The actual specification may
differ from the ICE chip specifications.
7. Do not start the emulator with an OTP device in the
programming socket. The emulator may not start up
correctly and the device may become corrupted.
8. A shorted OTP device can crash the emulator when
inserted into the OTP programming socket. If a part is
inserted in such a way as to cause a temporary short,
then functionality is lost. An attempt to perform
BLANK CHECK on such a part causes the hourglass to
appear continuously. The Windows application must
be reset and restarted.
9. Do not press the emulator’s MASTER RESET when
the ICEBOX is in the OTP dialog for programming. If
MASTER RESET is pressed while the GUI is
performing OTP programming, close the OTP dialog
box and reopen it to reload the information back to the
hardware.
Notes: The MASTER RESET is physically located on the inside
of the ICEBOX, and is not to be confused with the RESET
button on the outside of the unit.
In this instance, he ICEBOX is really idle, although the
Command Status indicates PROCESSING after the GUI
reestablishes the communication link when Retry is
selected in the Out of Synchronization with the Emulator
dialog box.
10. 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.
11. 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.
12. 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.
13. 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.
