13.3.10 Minute Alarm Register (RMINAR)
The minute alarm register (RMINAR) is an 8-bit read/write register, and an alarm register
corresponding to the BCD-coded minute section counter RMINCNT of the RTC. When the ENB
bit is set to 1, a comparison with the RMINCNT value is performed. From among the
RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/RMONAR registers, the counter and alarm
register comparison is performed only on those with ENB bits set to 1, and if each of those
coincide, an RTC alarm interrupt is generated.
The range of minute 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.
