I Clock supplying function
The clock supplying function is the function supplying the timer for the oscillation stabilization
wait time and the operation clocks to some peripheral functions. Table 9.1-2 "Clock cycles
supplied by timebase timer" lists the cycles of the clocks supplied by the timebase timer to
individual peripheral functions.

Function to which
clock is supplied
Oscillation stabilization

Watchdog timer
HCLK: Oscillation clock
The value during operation of the oscillation clock at 4 MHz is shown in ( ).
Reference:
Because the oscillation cycle immediately after the start of oscillation is unstable, the
oscillation stabilization wait time is merely a guideline.
