15. Time Base Timer
The time base timer is an 18-bit free-run timer that counts up in synchronization with the internal count clock
(base oscillator divided by 2) . It functions as an interval timer with a selection of four types of time intervals.
Other functions of this timer also include output of a timer signal for the oscillator stabilization wait time and an
operating clock signal for the watchdog timer.
