IMF (ICF) Setting Timing in Compare-Match: The IMF bit and CMF bit are set to 1 in the
timer status register (TSR) by the compare-match signal generated when the general register (GR)
output compare register (OCR), or cycle register (CYLR) value matches the timer counter (TCNT)
value. The compare-match signal is generated in the last state of the match (when the matched
TCNT count value is updated).
The timing in this case is shown in figure 11.38.
