Write has no meaning or effect in the normal mode; only writable in
special modes (SMODN = 0).
The period of the first count after a write to the TCNT registers may
be a different size because the write is not synchronized with the
prescaler clock.
Read or write anytime.
If for any reason the timer is not active, there is no 64 clock for the
pulse accumulator since the E 64 is generated by the timer prescaler.

channel flag, CnF, to be cleared. For TFLG2 ($8F), any access
to the TCNT register ($84, $85) clears the TOF flag. Any
