Figure 12.3 shows the TCNT count timing with internal clock source. Figure 12.4 shows the
TCNT incrementation timing with external clock source. The pulse width of the external clock for
incrementation at signal edge must be at least 1.5 system clock (φ) periods, 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.
