9.3.3
When the CCLR1 and CCLR0 bits in TCR are both set to 1, the timer counter is cleared on the
rising edge of an external reset input. Figure 9.7 shows the timing of this operation. The timer
reset pulse width must be at least 1.5 system clock (ø) periods.
9.3.4
The overflow flag (OVF) is set to 1 when the timer count overflows (changes from H'FF to H'00).
Figure 9.8 shows the timing of this operation.
