15.3.15 Year Alarm Register (RYRAR)
RYRAR is an alarm register corresponding to the year counter RYRCNT. When the YAEN bit in
RCR3 is set to 1, a comparison with the RYRCNT 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 year alarm which can be set is 0000 to 9999 (decimal). Errant operation will result if
any other value is set.
RYRAR is a 16-bit readable/writable register. The contents are not initialized by a power-on reset
or manual reset, or in standby mode.
