2. Timebase Timer
The timebase timer is a 18-bit free-run counter (timebase counter) for counting up in synchronization to the
internal count clock (divided-by-2 of oscillation) with an interval timer function for selecting an interval time from
four types of 212/HCLK, 214/HCLK, 216/HCLK, and 219/HCLK.
The timebase timer also has a function for supplying operating clocks for the timer output for the oscillation
stabilization time or the watchdog timer etc.
