Description
Output Compare Interrupt B Enable
Selects whether to enable output compare interrupt B
request (OCIB) when output compare flag B (OCFB) in
TCSR is set to 1.
0: OCIB requested by OCFB is disabled
1: OCIB requested by OCFB is enabled
Timer Overflow Interrupt Enable
Selects whether to enable a free-running timer overflow
request interrupt (FOVI) when the timer overflow flag (OVF)
in TCSR is set to 1.
0: FOVI requested by OVF is disabled
1: FOVI requested by OVF is enabled
This bit is always read as 1 and cannot be modified.
Description
This status flag indicates that the FRC value has been
transferred to ICRA by means of an input capture signal.
When BUFEA = 1, ICFA indicates that the old ICRA value
has been moved into ICRC and the new FRC value has
been transferred to ICRA.
[Setting condition]
When an input capture signal causes the FRC value to be
transferred to ICRA
[Clearing condition]
Read ICFA when ICFA = 1, then write 0 to ICFA
