  Date Alarm Register (RDAYAR) 
RDAYAR is an alarm register corresponding to the BCD-coded date counter RDAYCNT. When 
the ENB bit is set to 1, a comparison with the RDAYCNT 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 01 through 31 + ENB bits (practically in BCD), otherwise operation 
errors occur.
