Section 17 Realtime Clock (RTC)
17.3.10 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
coincide, an alarm flag of RCR1 is set to 1.
The range of minute alarm, which can be set, is 00 to 59 (decimal). Errant operation will result if
any other value is set.
The ENB bit in RMINAR is initialized by a power-on reset. The remaining RMINAR fields are
not initialized by a power-on reset or manual reset, or in standby mode.
