13.5.4
TCNT is cleared when compare match A or B occurs, depending on the settings of the CCLR1
and CCLR0 bits in TCR and the TMRIS bit in TCCR. Figure 13.8 shows the timing of this
operation.
13.5.5
TCNT is cleared at the rising edge, falling edge, low level, or high level of an external reset input,
depending on the settings of the CCLR1 and CCLR0 bits in TCR and the TMRIS bit in TCCR.
The clear pulse width must be at least 1.5 states for a single edge and at least 2.5 states for both
edges. Figure 13.9 shows the timing of this operation.
