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 range of date can be set is 01 to 31 (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.
RDAYCNT is not initialized by a power-on reset or manual reset, or in standby mode.
The RDAYCNT range that can be set changes with each month and in leap years. Please confirm
the correct setting.
