Note:
1. The CPU write to the compare registers may take place at any time, but a compare only occurs at
the timer state T01. Thus a 4-cycle difference may exist between the write to the compare register
and the actual compare.
2. The output compare ag is set at the timer state T11 that follows the comparison match ($F547 in
this example).

OVERFLOW
FLAG (TOF)
The TOF bit is set at timer state T11 (transition of counter from $FFFF to $0000).
It is cleared by a read of the timer status register during the internal processor
clock high time followed by a read of the counter low register.
