Fig 11-2: PCA capture mode with positive edge
11.2.2 Negative edge capture mode:
The external input pins CC0 through CC4 are sampled for a 1-to 0 transition. When a negative 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.

11.2.3 Both positive and negative edge capture mode:
The external input pins CC0 through CC4 are sampled for a 0-to-1 or 1-to-0 transition. When a
positive edge or negative 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.
