Section 16 Realtime Clock (RTC)
16.2.6
The date counter (RDAYCNT) is an 8-bit read/write register used for setting/counting in the
BCD-coded date section of the RTC. The count operation is performed by a carry for each day of
the hour counter.
The settable range is 01 to 31 in decimal. If other values are set, correct operation is not provided.
When modifying RDAYCNT, check that the count operation has been halted with the START bit
in RCR2.
RDAYCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
The settable RDAYCNT range differs according to the month and leap year. Please confirm the
correct setting.
16.2.7
The month counter (RMONCNT) is an 8-bit read/write register used for setting/counting in the
BCD-coded month section of the RTC. The count operation is performed by a carry for each
month of the date counter.
The settable range is 01 to 12 in decimal. If other values are set, correct operation is not provided.
When modifying RMONCNT, check that the count operation has been halted with the START bit
in RCR2.
RMONCNT is not initialized by a power-on reset or manual reset, or in standby mode, and the
operation is continued.
