13.5.5
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 clear pulse width must be at least 1.5 states. Figure 13.8
shows the timing of this operation.
13.5.6
The OVF in TCSR is set to 1 when TCNT overflows (changes from H'FF to H'00). Figure 13.9
shows the timing of this operation.
