The RTCC2 register is an 8-bit register that is used to control the interval interrupt function.
RTCC2 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
The RSUBC register is a 16-bit register that counts the reference time of 1 second of the real-time counter. It
takes a value of 0000H to 7FFFH and counts 1 second with a clock of 32.768 kHz.
RSUBC can be set by a 16-bit memory manipulation instruction.
Reset signal generation clears this register to 0000H.
Cautions 1. When a correction is made by using the SUBCUD register, the value may become 8000H
Cautions 1. Change ICT2, ICT1, and ICT0 when RINTE = 0.

2. This register is also cleared by reset effected by writing the second count register.
3. The value read from this register is not guaranteed if it is read during operation, because
