FRC can be cleared when compare-match A occurs. Figure 11.6 shows the timing of this
operation.
11.3.4
Input Capture Input Timing
An internal input capture signal is generated from the rising or falling edge of the signal at the
input capture pin, as selected by the corresponding IEDGx (x = A to D) bit in TCR. Figure 11.7
shows the usual input capture timing when the rising edge is selected (IEDGx = 1).
If the upper byte of ICRA/B/C/D is being read when the corresponding input capture signal
arrives, the internal input capture signal is delayed by one system clock ( ) period. Figure 11.8
shows the timing for this case.
