Watch timer
The watch timer is a 15-bit timer that uses sub-clocks and can generate an interval interrupt. It can also be used
as the watchdog timer clock source and sub-clock oscillation wait time.
Features of the watch timer :
Provides the watchdog timer clock source
Sub-clock oscillation stabilization wait timer function
Interval timer function that generates interrupts in a given cycle
