NOTES:
1. To enter into IDLE mode, PCON must be set to ‘01H’.
2. To enter into STOP1,2 mode, PCON must be set to ‘03H’.
(In STOP1,2 mode, PCON register is cleared automatically by interrupt or reset)
3. When PCON is set to ‘03H’, if SCCR[7] is set to ‘1’, it enters the STOP1 mode. if SCCR[7] is cleared to
‘0’, it enters the STOP2 mode.
4. The different thing in STOP 1,2 is only clock operation of internal 8kHz WDTRC OSC during STOP mode
operating.
5. The PCON register is automatically cleared by a release signal in STOP/IDLE mode.
6. Three or more NOP instructions must immediately follow the instruction that make the device enter into
STOP/IDLE mode. Refer to the following examples.
