Section 17 Realtime Clock (RTC)
17.3.9
RSECAR is an alarm register corresponding to the BCD coded second counter RSECCNT of the
RTC. When the ENB bit is set to 1, a comparison with the RSECCNT value is performed. From
among RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/RMONAR/RCR3, the counter and
alarm register comparison is performed only on those with ENB bits set to 1, and if each of those
coincide, an alarm flag of RCR1 is set to 1.
The range of second alarm which can be set is 00 to 59 (decimal) + ENB bits. Errant operation
will result if any other value is set.
The ENB bit in RSECAR is initialized to 0 by a power-on reset. The remaining RSECAR fields
are not initialized by a power-on reset or manual reset, or in standby mode.
17.3.10 Minute Alarm Register (RMINAR)
RMINAR is an alarm register corresponding to the minute counter RMINCNT. When the ENB bit
is set to 1, a comparison with the RMINCNT value is performed. From among
RSECAR/RMINAR/RHRAR/RWKAR/RDAYAR/RMONAR/RCR3, the counter and alarm
register comparison is performed only on those with ENB bits set to 1, and if each of those
coincide, an alarm flag of RCR1 is set to 1.
The range of minute alarm which can be set is 00 to 59 (decimal). Errant operation will result if
any other value is set.
The ENB bit in RMINAR is initialized by a power-on reset. The remaining RMINAR fields are
not initialized by a power-on reset or manual reset, or in standby mode.
