(2) RTC control register 1 (RTCC1)
Notes 1. 80H or 81H, depending on the value of the RTCF bit.
Remark
The RTCC1 register is an 8-bit register that controls the operation of the real-time counter. This register can be
read or written in 8-bit or 1-bit units.
This register is set to 8xH after reset.
2. The RTCF bit is a read-only bit.
The timing of generating an interrupt request set by the INTS3 to INTS0 bits is determined by the
setting of the CKS bit of the RTCC0 register, as follows.
When CKS bit = 0
When CKS bit = 1
