Input capture/compare match flag A
0 [Clearing condition]
Read IMFA when IMFA = 1, then write 0 in IMFA
DMAC activated by IMIA interrupt (channels 0 to 3 only).
1 [Setting conditions]
TCNT = GRA when GRA functions as an output compare
register.
TCNT value is transferred to GRA by an input capture
signal, when GRA functions as an input capture register.
Input capture/compare match flag B
0 [Clearing condition]
Read IMFB when IMFB = 1, then write 0 in IMFB
1 [Setting conditions]
TCNT = GRB when GRB functions as an output compare
register.
TCNT value is transferred to GRB by an input capture
signal, when GRB functions as an input capture register.
Overflow flag
0 [Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
1 [Setting condition]
TCNT overflowed from H'FFFF to H'0000
Note: * Only 0 can be written, to clear the flag.
