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.

• 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
