12.4.4 Input Capture Input Timing
Either the rising edge or falling edge can be selected for input capture input using the IEDG bit in
TCR. Figure 12.8 shows the timing when the rising edge is selected (IEDG = 1).

When the input capture signal is input when FICR is read (upper-byte read), the input capture
signal is delayed by one cycle of PÏ. Figure 12.9 shows the timing.
