Input capture timing
The rising or falling edge is selected for input capture by bits IEDGA to IEDGD in TCRX.
Figure 9.24 shows the timing when the rising edge is selected (IEDGA/B/C/D = 1).
If the input at the input capture pin occurs while the upper byte of the corresponding input
capture register (ICRA to ICRD) is being read, the internal input capture signal is delayed by
one system clock ( ). Figure 9.25 shows the timing.
