15. Timebase Timer
The timebase timer is an 18-bit free run counter (timebase counter) that counts up in synchronization with the
internal count clock signal (base oscillator
×
2) , and functions as an interval timer with a choice of four types of
time intervals. Other functions provided by this module include timer output for the oscillator stabilization wait
period, and operating clock signal feed for other timer circuits such as the watchdog timer.
