13.3.14 Month Alarm Register (RMONAR)
The month alarm register (RMONAR) is an 8-bit read/write register, and an alarm register
corresponding to the BCD-coded month section counter RMONCNT of the RTC. When the ENB
bit is set to 1, a comparison with the RMONCNT value is performed. From among the registers
RSECAR, RMINAR, RHRAR, RWKAR, RDAYAR, RMONAR, 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 month can be set 01 to 12 (decimal). Errant operation will result if any other value is
set.
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.
