Figure 11.8 Input Capture Signal Timing (Input Capture Input when ICRA/B/C/D Is Read)
Buffered Input Capture Input Timing
ICRC and ICRD can operate as buffers for ICRA and ICRB.
Figure 11.9 shows how input capture operates when ICRA and ICRC are used in buffer mode and
IEDGA and IEDGC are set to different values (IEDGA = 0 and IEDGC = 1, or IEDG A = 1 and
IEDGC = 0), so that input capture is performed on both the rising and falling edges of FTIA.
