Function of Clock Supply
The clock supply function supplies the operating clock to the timer for oscillation stabilization wait time
and some peripheral functions. Table 9.1-2 shows the clock cycle supplied from the timebase timer to each
peripheral.

Wait Time
Watchdog timer
HCLK: Oscillation clock
The value in parentheses is applicable when the oscillation clock operates at 6 MHz.
Reference:
Because oscillation cycles is unstabled after oscillation starts, the oscillation stabilization wait time is
listed for reference.
