Section 15 Realtime Clock (RTC)
The range of hour can be set is 0 to 23 (decimal). Errant operation will result if any other value is
set. Carry out write processing after stopping the count operation with the START bit in RCR2.
RHRCNT is an 8-bit readable/writable register and not initialized by a power-on reset or manual
reset, or in standby mode.
15.3.5
RWKCNT is used for setting/counting day of week section. The count operation is performed by a
carry for each day of the date counter.
The range for day of the week can be set is 0 to 6 (decimal). Errant operation will result if any
other value is set. Carry out write processing after stopping the count operation with the START
bit in RCR2.
