Section 12 16-Bit Free-Running Timer (FRT)
12.5.4
The rising or falling edge can be selected for the input capture input timing by the IEDGA to
IEDGD bits in TCR. Figure 12.7 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 ( ). Figure 12.8 shows the timing for this case.
