Section 13 Realtime Clock (RTC)
13.3.4
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 range of hour can be set is 00 to 23 (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.
RHRCNT is not initialized by a power-on reset or manual reset, or in standby mode.
13.3.5
The day of the week counter (RWKCNT) is an 8-bit read/write register used for setting/counting
in the BCD-coded day of week section of the RTC. 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 halting the count operation with the START bit
in RCR2.
RWKCNT is not initialized by a power-on reset or manual reset, or in standby mode.
