15.3.12 Day of Week Alarm Register (RWKAR)
RWKAR is an alarm register corresponding to the BCD coded day of week counter RWKCNT.
When the ENB bit is set to 1, a comparison with the RWKCNT value is performed. From among
RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/RMONAR/RCR3, the counter and alarm
register comparison is performed only on those with ENB bits set to 1, and if each of those
coincides, an alarm flag of RCR1 is set to 1.
The assignable range is from 0 through 6 + ENB bits (practically in BCD), otherwise operation
errors occur.
The ENB bit in RWKAR is initialized by a power-on reset or in deep standby mode. The other bits
are not initialized by a power-on reset or manual reset, or in deep standby and software standby
modes.
