12.5.1
Figure 12.5 shows the TCNT count timing for internal clock input. Figure 12.6 shows the TCNT
count timing for external clock input. Note that the external clock pulse width must be at least 1.5
states for incrementation at a single edge, and at least 2.5 states for incrementation at both edges.
The counter will not increment correctly if the pulse width is less than these values.
