12.3 Registers

Sep 30, 2010
The real-time counter is controlled by the following 18 registers.
(1) Real-time counter control register 0 (RC1CC0)
(2) Real-time counter control register 1 (RC1CC1)
The RC1CC0 register selects the real-time counter input clock.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
The RC1CC1 register is an 8-bit register that starts or stops the real-time counter, controls the RTCCL and
RTC1HZ pins, selects the 12-hour or 24-hour system, and sets the fixed-cycle interrupt function.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
Cautions 1. Follow the description in 12.4.8 Initializing real-time counter when stopping (RC1PWR =
