The example assumes that 8 MHz is being applied to the X
IN
pin and 32 kHz to the X
CIN
pin. The
φ
indicates the internal clock.

Notes 1:
When the STP state is ended, a delay of approximately 4 ms is automatically generated by timer 3 and timer 4.
2:
The delay after the STP state ends is approximately 1s.
3:
When the internal clock
φ
divided by 8 is used as the timer count source, the frequency of the count source is 2 kHz.
The program must
allow time for 8 MHz
oscillation to stabilize
