Section 15 Realtime Clock (RTC)
15.3.14 Month Alarm Register (RMONAR)
RMONAR is an alarm register corresponding to the month counter RMONCNT. When the ENB
bit is set to 1, a comparison with the RMONCNT value is performed. From among
RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/ and 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 month alarm which can be set is 1 to 12 (decimal). Errant operation will result if any
other value is set.
RMONAR is an 8-bit readable/writable register. The ENB bit in RMONAR is initialized by a
power-on reset. The remaining RMONAR fields are not initialized by a power-on reset or manual
reset, or in standby mode.
