External Clock: If external clock input (TMCI) is selected, the timer counter can increment on
the rising edge, the falling edge, or both edges of the external clock signal. Figure 9.3 shows
incrementation on both edges of the external clock signal.
The external clock pulse width must be at least 1.5 system clock (ø) periods for incrementation on
a single edge, and at least 2.5 system clock periods for incrementation on both edges. The counter
will not increment correctly if the pulse width is shorter than these values.
