(4) Real-time counter control register 2 (RTCC2)
RTCC2
Symbol
The RTCC2 register is an 8-bit register that is used to control the interval interrupt function and the RTCDIV pin.
RTCC2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Cautions 1. Change ICT2, ICT1, and ICT0 when RINTE = 0.

2. RCLOE0 and RCLOE2 must not be enabled at the same time.
