0
R/W
Carry Interrupt Enable Flag
Enables or disables interrupt generation when the carry
flag (CF) is set to 1.
0: Carry interrupt is not generated when CF flag is set
to 1
1: Carry interrupt is generated when CF flag is set to 1
3
AIE
0
R/W
Alarm Interrupt Enable Flag
Enables or disables interrupt generation when the
alarm flag (AF) is set to 1.
0: Alarm interrupt is not generated when AF flag is set
to 1
1: Alarm interrupt is generated when AF flag is set to 1
2 — Undefined
R
Reserved
The initial value of these bits is undefined. A write to
these bits is invalid, but the write value should always
be 0.
1
CRF
Undefined R
Carry Ready Flag
Indicates whether or not RSECCNT (second counter)
is in the state of the carry ready period.
This flag is set to 1 when the second counter value is
to be incremented after the 1 Hz bit in R64CNT (64 Hz
counter) has changed from 1 to 0.
However, writing to this bit is invalid, the write value
should always be 0.
0: Not carry ready period
[Clearing condition]
When RSECCNT is not in carry ready period
1: Carry ready period
[Setting condition]
When RSECCNT is in carry ready period
