Section 15 Realtime Clock (RTC)
15.3.10 Minute Alarm Register (RMINAR)
RMINAR is an alarm register corresponding to the minute counter RMINCNT. When the ENB bit
is set to 1, a comparison with the RMINCNT 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 59 + ENB bits (practically in BCD), otherwise operation
errors occur.
The ENB bit in RMINAR 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.
