The rising or falling edge can be selected for the input capture input timing by the IEDGA to
IEDGD bits in TCR. Figure 10.7 shows the usual input capture timing when the rising edge is
selected.
If the corresponding input capture signal is input when ICRA to ICRD are read, the input capture
signal is delayed by one system clock (φ). Figure 10.8 shows the timing for this case.
