7 ICFA 0 R/(W)*

Input Capture Flag A

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. Only 0 can be
written to this bit to clear the flag.

[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
