16.2.12 Day of the Week Alarm Register (RWKAR)
The day of the week alarm register (RWKAR) is an 8-bit read/write alarm register that
corresponds to the BCD-coded day of week section counter RWKCNT of the RTC. When the
ENB bit is set to 1in RWKAR, the RWKAR value and RWKCNT value are compared. In this
way, the RSECAR, RMINAR, RHRAR, RWKAR, RDAYAR, and RMONAR registers are
checked, and when the ENB bit is set to 1, the alarm register and the corresponding counter are
compared. If all values in the specified alarm registers and the corresponding counters match, an
RTC alarm interrupt is generated.
The settable range is “0 to 6 in decimal + ENB bit”. If other values are set, correct operation is not
provided.
Only the ENB bit in RWKAR is initialized to 0 by a power-on reset, and the other bits are not
initialized. The RWKAR contents are retained after a manual reset or in standby mode.
Days of the week are coded as shown in table 16.4.

16.2.13 Date Alarm Register (RDAYAR)
The date alarm register (RDAYAR) is an 8-bit read/write alarm register that corresponds to the
BCD-coded date section counter RDAYCNT of the RTC. When the ENB bit is set to 1in
RDAYAR, the RDAYAR value and RDAYCNT value are compared. In this way, the RSECAR,
