7.12 Watchdog Timer
A watchdog timer is provided to detect a CPU runaway. This watchdog timer generates a non-maskable or
maskable interrupt unless it is cleared by software within a specified interval time. Once enabled to operate, the
watchdog timer cannot be stopped by software. Whether the interrupt by the watchdog timer or the interrupt input
from the NMI pin takes precedence can be specified.
