9. Watchdog Timer and Timebase Timer
The watchdog timer consists of a 2-bit watchdog counter, a control register, and a watchdog reset controller.
The watchdog counter uses the carry-up signal from the 18-bit timebase timer as its clock source.
In addition to the 18-bit timer, the timebase timer contains an interval interrupt control circuit. The timebase
timer uses the main clock, regardless of the value of the MCS bit in the CKSCR register.
