The rising or falling edge can be selected for the input capture input timing by the IEDGA to
IEDGD bits in TCR. Figure 9.7 shows the usual input capture timing when the rising edge is
selected.
If ICRA to ICRAD are read when the corresponding input capture signal arrives, the internal input
capture signal is delayed by one system clock (φ). Figure 9.8 shows the timing for this case.
