(4) Real-time counter control register 3 (RC1CC3)
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 12.4.7 Changing INTRTC2 interrupt setting during the real-time counter operation
RC1CC3
2. The RTCDIV output operates as follows when the CLOE2 bit setting is changed.
3. See 12.4.7 Changing INTRTC2 interrupt setting during the real-time counter operation
After reset: 00H
• When changed from 0 to 1: A pulse set by the CKDIV bit is output after two clocks (2 x
• When changed from 1 to 0: Output of the RTCDIV output is stopped after two clocks (2
when rewriting the RINTE bit during real-time counter operation (RC1PWR bit = 1).
when rewriting the ICT2 to ICT0 bits while the real-time counter operates (RC1PWR bit =
1).
