15.3.15 Year Alarm Register (RYRAR)
The year alarm register (RYRAR) is a 16-bit readable/writable register, and 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. For alarm registers RSECAR, RMINAR,
RHRAR, RWKAR, RDAYAR, and RMONAR, a comparison with the corresponding counter
value is performed for those whose ENB bit is set to 1, and for RCR3, a comparison is performed
when the YAEN bit is set to 1. If all of those match, an RTC alarm interrupt is generated.
The range of year alarm that can be set is 0000 to 9999 (decimal). Errant operation will result if
any other value is set.
The RYRAR contents are not initialized by a power-on reset or manual reset, or in standby mode.
