14.3.11 Hour Alarm Register (RHRAR)
RHRAR is an alarm register corresponding to the BCD coded hour counter RHRCNT of the RTC.
When the ENB bit is set to 1, a comparison with the RHRCNT 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 00 through 23 + ENB bits (practically in BCD), otherwise operation
errors occur.
