When the OC7Mn bit is set, a successful OC7 action will override a
successful OC[6:0] compare action during the same cycle; therefore, the
OCn action taken will depend on the corresponding OC7D bit.
The 16-bit main timer is an up counter.
A full access for the counter register should take place in one clock cycle.
A separate read/write for high byte and low byte will give a different result
than accessing them as a word.
Read anytime.
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.
TEN — Timer Enable
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.
