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 clear pulse width must be at least 1.5 states. Figure 12-7 shows the timing of this operation.
12.3.4
The 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.
