ICF — Input Capture Flag
OCF — Output Compare Flag
TOF — Timer Overflow Flag
The ICF bit is automatically set when an edge of the selected polarity
occurs on the PD7/TCAP pin. Clear the ICF bit by reading the timer
status register with ICF set, and then reading the low byte of the input
capture registers. Reset has no effect on ICF.
The OCF bit is automatically set when the value of the timer registers
matches the contents of the output compare registers. Clear the OCF
bit by reading the timer status register with OCF set, and then reading
the low byte of the output compare registers. Reset has no effect on
OCF.
The TOF bit is automatically set when the 16-bit counter rolls over
from $FFFF to $0000. Clear the TOF bit by reading the timer status
register with TOF set, and then reading the low byte of the timer
registers. Reset has no effect on TOF.
