Description
Year Alarm Enable
When this bit is set to 1, comparison of the year
alarm register (RYRAR) and the year counter
(RYRCNT) 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 set to 1, and if each of those coincide, an
RTC alarm interrupt is generated.
Reserved
These bits are always read as 0. The write value
should always be 0.
