Timing of Compare-Match Clear
Depending on the CCLR1 and CCLR0 bits in the TCR, the timer counter can be cleared when
compare-match A or B occurs. Figure 11-5 shows the timing of this operation.
11.3.3 External Reset of TCNT
When the CCLR1 and CCLR0 bits in the TCR are both set to “1,” the timer counter is cleared on
the rising edge of an external reset input. Figure 11-6 shows the timing of this operation.
