CHAPTER 11 TIMEBASE TIMER
■ Clock Supply
The timebase timer supplies an operation clock to the resources such as an oscillation stabilization wait
time timer, PPG timer, and watchdog timer. Table 11.1-2 shows the clock cycles supplied from the
timebase timer to each resource.

HCLK: Oscillation clock
The parenthesized values are provided at 4-MHz oscillation clock.
*:As the oscillation cycle is unstable immediately after oscillation starts, standard oscillation
stabilization wait time values are given as a guide.
