Section 13 8-Bit Timers (TMR)
13.5
13.5.1
Figure 13.3 shows the count timing for internal clock input. Figure 13.4 shows the count timing
for external clock signal. 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.
