(4) Real-time counter control register 3 (RC1CC3)
Remark
The RC1CC3 register is an 8-bit register that controls the interval interrupt function and RTCDIV pin.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
Cautions 1. See 11.4.7 Changing INTRTC2 interrupt setting during clock operation when rewriting
RC1CC3
2. The RTCDIV output operates as follows when the CLOE2 bit setting is changed.
3. See 11.4.7 Changing INTRTC2 interrupt setting during clock operation when rewriting
When RTC back up mode, Interval interrupt and RTCDIV pin output are stop.
After reset: 00H
• When changed from 0 to 1: A pulse set by the CKDIV bit is output after two clocks
• When changed from 1 to 0: Output of the RTCDIV output is stopped after two clocks
