14.3.18 RTC Control Register 3 (RCR3)

When the ENB bit is set to 1, RCR3 performs a comparison with the RYRCNT. 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.
