10.6 16-Bit Input Capture Operations
When detecting the specified valid edge, the 16-bit input capture can take a 16-bit free-
run timer value in the capture register to generate an interrupt.

Figure 10.6-1 shows an example of the input capture take-in timings for 0ch. Other channels
also perform the same operation.
