Watch-Dog Timer
(WDT). The Z90102/3/4 is equipped
with a permanently enabled Watch-Dog Timer which must
be refreshed every 12 ms. Failure to refresh the timer re-
sults in a reset of the device. The WDT is permanently en-
abled and is initially reset upon POR. Every subsequent
WDT instruction resets the timer. The Watch-Dog Timer
may or may not be enabled during the STOP Mode. The
instruction WDT 4F (HEX) enables the timer during HALT.
If the WDH instruction is used, and if the HALT Mode is not
released and the Watch-Dog Timer is not retriggered (by
the WDT instruction) within 12 ms, a device reset occurs.
The WDT instruction affects the Z (Zero) S (Sign), and V
(Overflow) flags. WDT does not run during STOP Mode.
