9. Watchdog Timer and Timebase Timer Functions
The watchdog timer consists of a 2-bit watchdog counter using carry signals from the 18-bit timebase timer as
the clock source, a control register, and a watchdog reset controller.
In addition to an 18-bit timer, the timebase timer consists of a circuit for controlling interval interrupts. Note that
the timebase timer uses the main clock regardless of the status of the MCS bit within the CKSCR register.
