11.2.14 Month Alarm Register (RMONAR)
RMONAR is an 8-bit readable/writable register used as an alarm register for the RTC's BCD-
coded month value counter, RMONCNT. When the ENB bit is set to 1, the RMONAR value is
compared with the RMONCNT value. Comparison between the counter and the alarm register is
performed for those registers among RSECAR, RMINAR, RHRAR, RWKAR, RDAYAR, and
RMONAR in which the ENB bit is set to 1, and the RCR1 alarm flag is set when the respective
values all match.
The setting range is decimal 01 to 12 + ENB bit. The RTC will not operate normally if any other
value is set.
The ENB bit in RMONAR is initialized by a power-on reset. The other fields in RMONAR are
not initialized by a power-on or manual reset, or in standby mode.
Bits 6 and 5 are always read as 0. A write to these bits is invalid, but the write value should always
be 0.
11.2.15 RTC Control Register 1 (RCR1)
RCR1 is an 8-bit readable/writable register containing a carry flag and alarm flag, plus flags to
enable or disable interrupts for these flags.
The CIE and AIE bits are initialized to 0 by a power-on or manual reset; the value of bits other
than CIE and AIE is undefined. In standby mode RCR1 is not initialized, and retains its current
value.
