15.3.13 Date Alarm Register (RDAYAR)
RDAYAR is an alarm register corresponding to the date counter RDAYCNT. When the ENB bit
is set to 1, a comparison with the RDAYCNT 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 date alarm which can be set is 1 to 31 (decimal). Errant operation will result if any
other value is set. The RDAYCNT range that can be set changes with some months and in leap
years. Please confirm the correct setting.
RDAYAR is an 8-bit readable/writable register. The ENB bit in RDAYAR is initialized by a
power-on reset. The remaining RDAYAR fields are not initialized by a power-on reset or manual
reset, or in standby mode.
