TCNT is cleared when compare-match A or compare-match B occurs, depending on the setting of
the CCLR1 and CCLR0 bits in TCR. Figure 11.8 shows the timing of clearing the counter by a
compare-match.
11.5.5
TCNT is cleared at the rising edge of an external reset input, depending on the settings of the
CCLR1 and CCLR0 bits in TCR. The width of the clearing pulse must be at least 1.5 states. Figure
11.9 shows the timing of clearing the counter by an external reset input.
