How to disable watchdog timer
When not using the watchdog timer, it can be disabled. When the
watchdog timer is disabled, it
s operation stops and no watchdog
timer interrupt has been generated.
Setting for disabling the watchdog timer is possible by writing
79
16
and
50
16
to the particular function select register 2 (address 64
16
)
sequentially with the following instructions:
MOVMB/STAB instruction, or
MOVM/STA instruction (m = 1)
If any method other than above has been adopted in order to access
(in other words, read/write) the particular function select register 2,
the watchdog timer will not be disabled until reset operation is per-
formed. (Also, reset is the only one method to remove the setting for
disabling the watchdog timer.)
