IC1F – Input Capture 1 Flag
1 = Flag set when selected polarity edge is sensed by input capture
1 edge detector
0 = Flag cleared when TSR and input capture 1 registers low byte
is accessed
IC2F – Input Capture 2 Flag
1 = Flag set when selected polarity edge is sensed by input capture
2 edge detector
0 = Flag cleared when TSR and input capture 2 registers low byte
is accessed
OC1F – Output Compare 1 Flag
1 = Flag set when output compare register 1 contents match the
free-running counter contents
0 = Flag cleared when TSR and output compare register 1 low byte
are accessed
