Section 10 8-Bit Timers
Bits 3 to 0—Output Select 3 to 0 (OS3 to OS0): These bits specify how the timer output level is
to be changed by a compare match of TCOR and TCNT.
Bits OS3 and OS2 select the effect of compare match B on the output level, bits OS1 and OS0
select the effect of compare match A on the output level, and both of them can be controlled
independently.
Note, however, that priorities are set such that: toggle output > 1 output > 0 output. If compare
matches occur simultaneously, the output changes according to the compare match with the higher
priority.
Timer output is disabled when bits OS3 to OS0 are all 0.
After a reset, the timer output is 0 until the first compare match event occurs.
