Cautions 1. Writing 0 to the RTCE bit while the RTCE bit is 1 is prohibited. Clear the RTCE bit by
RC1CC1
2. The RTC1HZ output operates as follows when the CLOE1 bit setting is changed.
3. See 12.4.1 Initial settings and 12.4.2 Rewriting each counter during the real-time counter
4. See 12.4.4 Changing INTRTC0 interrupt setting during the real-time counter operation

when rewriting the CT2 to CT0 bits while the real-time counter operates (RC1PWR bit =
1).
• When changed from 0 to 1: The RTC1HZ output outputs a 1 Hz pulse after two clocks
• When changed from 1 to 0: The RTC1HZ output is stopped (fixed to low level) after
