R64CNT is not initialized by a power-on reset or manual reset, or in standby mode.
Bit 7 always reads 0.
12.2.2
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 that can be set is 00–59 (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, or
perform a write using the carry flag as shown in figure 12.2.
RSECCNT is not initialized by a power-on reset or manual reset, or in standby mode.
12.2.3
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 that can be set is 00–59 (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, or
perform a write using the carry flag as shown in figure 12.2.
