(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.
Notes RCLOE0 and RCLOE2 must not be enabled at the same time.
Cautions 1. Change ICT2, ICT1, and ICT0 when RINTE = 0.
