Reset the watchdog timer after a watchdog timer interrupt occurs.
To change the interrupt control register while the interrupt request is disabled, follow the instructions
below.
Use the following instructions to set bits 1 to 7 in the IIOilR register to "0" (no interrupt requested).
AND, BCLR
The DMAII bit is indeterminate after reset. When using the DMAII bit to generate an interrupt, set the
interrupt control register after setting the DMACII bit to "0" (interrupt priority level 7 available for inter-
rupts).

When an interrupt request occurs while executing an instruction, the IR bit may not be set to "1"
(interrupt requested) and the interrupt may be ignored. If this is a problem, use the following instruc-
tions to change the register: AND, OR, BCLR, BSET
The IR bit may not change to "0" (no interrupt requested) depending on the instructions written. If this
is a problem, use the following instruction to change the register: MOV
