Second Counter (RSECCNT)

RSECCNT is the counter used for setting/counting the BCD-coded second value. The count operation is performed by a
carry for each second of the 64-Hz counter.
The assignable range is from 00 through 59 (practically in BCD); otherwise an operation error will occur. Carry out write
processing after stopping the count operation through the setting of the START bit in RCR2.

Minute Counter (RMINCNT)

RMINCNT is the counter used for setting/counting the BCD-coded minute value. The count operation is performed by a
carry for each minute of the second counter.
The assignable range is from 00 through 59 (practically in BCD); otherwise an operation error will occur. Carry out write
processing after stopping the count operation through the setting of the START bit in RCR2.
