Input capture signal timing
Input capture on the rising edge, falling edge, or both edges can be selected by settings in
TIOR. Figure 8-25 shows the timing when the rising edge is selected. The pulse width of the
input capture signal must be at least 1.5 system clocks for single-edge capture, and 2.5 system
clocks for capture of both edges.
