Figure 11.3 shows the TCNT count timing with internal clock source. Figure 11.4 shows the
TCNT incrementation timing with external clock source. The pulse width of the external clock for
incrementation at single edge must be at least 1.5 status, 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.
