will be transferred (ICRA and ICRC, or ICRB and ICRD) is being read when the input capture
input signal arrives, input capture is delayed by one system clock (ø). Figure 11.10 shows the
timing when BUFEA = 1.
11.5.6
The input capture flag, ICFA, ICFB, ICFC, or ICFD, is set to 1 by the input capture signal. The
FRC value is simultaneously transferred to the corresponding input capture register (ICRA, ICRB,
ICRC, or ICRD). Figure 11.11 shows the timing of setting the ICFA to ICFD flag.
