Timer Output Timing: When compare-match A or B occurs, the timer output changes as
specified by the output select bits (OS3 to OS0) in TCSR. Depending on these bits, the output can
remain the same, be set to 0, be set to 1, or toggle.
Figure 12.5 shows the timing when the output is set to toggle at compare-match A.
Timing of Compare-Match Clear: TCNT is cleared when compare-match A or B occurs,
depending on the setting of the CCLR1 and CCLR0 bits in TCR. Figure 12.6 shows the timing of
this operation.
