13.5.1
Figure 13.4 shows the TCNT count timing with an internal clock source. Figure 13.5 shows the
TCNT count timing with an external clock source. The pulse width of the external clock signal
must be at least 1.5 system clocks (φ) for a single edge and at least 2.5 system clocks (φ) for both
edges. The counter will not increment correctly if the pulse width is less than these values.
