16 Bit Timer Count Register
Timer Count Register (TCNT)
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. The period of the first count after a write to the TCNT
registers may be a different length because the write is not synchronized with the prescaler
clock.
