12.5.5
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
12.9 shows the timing of clearing the counter by an external reset input.
12.5.6
The OVF bit in TCSR is set to 1 when the TCNT overflows (changes from H'FF to H'00). Figure
12.10 shows the timing of OVF flag setting.
