11.2 PCA Compare/Capture mode
11.2.1
The external input pins CC0 through CC4 are sampled for a 0-to 1 transition. When a positive edge
transition is detected, hardware loads the 16-bit value of the PCA counter (CCCH, CCCL) into the
module’s capture registers (CCnDH, CCnDL). The resulting value in the capture registers reflects
the PCA timer value at the time a transition was detected on the CCn pin.
