FRC Clear Timing

FRC can be cleared when compare-match A occurs. Figure 11.6 shows the timing of this

operation.

Input Capture Input Timing

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).

Figure 11.7 Input Capture Signal Timing (Usual Case)

If the upper byte of ICRA to ICRD is being read when the corresponding input capture signal

arrives, the internal input capture signal is delayed by one system clock (

φ) period. Figure 11.8

shows the timing for this case.
