Fig. 79. State Transitions of System Clock
Reset
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 8ms is automatically generated by timer 3 and timer 4.
2: The delay after the STP state ends is approximately 2s.
3: When the internal clock
φ divided by 8 is used as the timer count source, the frequency of the count source is 2kHz.
The program must
allow time for 8MHz
