Reset the watchdog timer after a watchdog timer interrupt occurs.

27.7.5 Changing Interrupt Control Register

To change the interrupt control register while the interrupt request is denied, follow the instructions below.

Changing IR bit

The IR bit setting 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

Changing Bits Except IR Bit

When an interrupt request is generated 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 instructions

to change the register: AND, OR, BCLR, BSET

27.7.6 Changing IIOiIR Register (i = 0 to 5, 8 to 11)

Use the following instructions to set bits 1 to 7 in the IIOilR register to "0" (no interrupt requested): AND,

BCLR

27.7.7 Changing RLVL Register

The DMAII bit is indeterminate after reset. When using the DMAII bit to generate an interrupt, set the

interrupt control register after setting the DMAII bit to "0" (interrupt priority level 7 available for interrupts).
