Even when ICRC or ICRD is used as a buffer register, its input capture flag is set by the selected
transition of its input capture signal. For example, if ICRC is used to buffer ICRA, when the edge
transition selected by the IEDGC bit occurs on the FTIC input capture line, ICFC will be set, and
if the ICICE bit is set at this time, an interrupt will be requested. The FRC value will not be
transferred to ICRC, however. In buffered input capture, if either set of two registers to which data
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 ( ). Figure 11.10 shows the
timing when BUFEA = 1.
