Section 16 Realtime Clock (RTC)
16.2.3
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 settable range is 00 to 59 in decimal. If other values are set, correct operation is not provided.
When modifying RMINCNT, check that the count operation has been halted with the START bit
in RCR2.
RMINCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
16.2.4
The hour counter (RHRCNT) is an 8-bit read/write register used for setting/counting in the BCD-
coded hour section of the RTC. The count operation is performed by a carry for each 1 hour of the
minute counter.
The settable range is 00 to 23 in decimal. If other values are set, correct operation is not provided.
When modifying RHRCNT, check that the count operation has been halted with the START bit in
RCR2.
RHRCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
