Section 12 8-Bit Timers
12.3.3
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
12.7 shows the timing of this operation.
12.3.4
OVF in TCSR is set to 1 when the timer count overflows (changes from H'FF to H'00). Figure
12.8 shows the timing of this operation.
