RMINAR is an 8-bit readable/writable register. 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.
15.3.11 Hour Alarm Register (RHRAR)
RHRAR is an alarm register corresponding to the 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, the counter and alarm register
comparison is performed only on those with ENB bits and the YAEN bit in RCR3 set to 1, and if
each of those coincide, an RTC alarm interrupt is generated.
The range of hour alarm which can be set is 0 to 23 (decimal). Errant operation will result if any
other value is set.
RHRAR is an 8-bit readable/writable register. The ENB bit in RHRAR is initialized by a power-
