Remark
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 11.4.1 Initial settings and 11.4.2 Rewriting each counter during clock operation for

• When changed from 0 to 1: The RTC1HZ output outputs a 1 Hz pulse after two
• When changed from 1 to 0: The RTC1HZ output is stopped (fixed to low level) after
