13.3.2
The second counter (RSECCNT) is an 8-bit read/write register used for setting/counting in the
BCD-coded second section of the RTC. The count operation is performed by a carry for each
second of the 64-Hz counter.
The range of second can be set is 00 to 59 (decimal). Errant operation will result if any other value
is set. Carry out write processing after halting the count operation with the START bit in RCR2.
RSECCNT is not initialized by a power-on reset or manual reset, or in standby mode.
13.3.3
The minute counter (RMINCNT) is an 8-bit read/write register used for setting/counting in the
BCD-coded minute section of the RTC. The count operation is performed by a carry for each
minute of the second counter.
The range of minute can be set is 00 to 59 (decimal). Errant operation will result if any other value
is set. Carry out write processing after halting the count operation with the START bit in RCR2.
RMINCNT is not initialized by a power-on reset or manual reset, or in standby mode.
