13. Time-base timer
The time-base timer has a function that enables a selection of four interval times using 18-bit free-run counter
(time-base counter) with synchronizing to the internal count clock (two division of original oscillation). Further-
more, the function of timer output of oscillation stabilization wait or function supplying operation clocks for
watchdog timer are provided.
