Description
Carry Interrupt Enable Flag
When the carry flag (CF) is set to 1, the CIE bit enables
interrupts.
0: A carry interrupt is not generated when the CF flag is
1: A carry interrupt is generated when the CF flag is set
When the alarm flag (AF) is set to 1, the AIE bit allows
interrupts.
0: An alarm interrupt is not generated when the AF flag
1: An alarm interrupt is generated when the AF flag is
These bits are always read as 0. The write value should
always be 0.
The AF flag is set when the alarm time, which is set by
an alarm register (ENB bit in RSECAR, RMINAR,
RHRAR, RWKAR, RDAYAR, RMONAR, or RYRAR is
set to 1), and counter match.
0: Alarm register and counter not match
[Clearing condition]
When 0 is written to AF.
1: Alarm register and counter match *
[Setting condition]
When alarm register (only a register with ENB bit set to
1) and counter match
