The PCA0L register holds the low byte (LSB) of the 16-bit PCA Counter/Timer.
The PCA0H register holds the high byte (MSB) of the 16-bit PCA Counter/Timer. Note
the value read is actually from the snapshot register in order to synchronize it with PCA0L.
The PCA0CPLn register holds the low byte (LSB) of the 16-bit capture module n.
The PCA0CPHn register holds the high byte (MSB) of the 16-bit capture module n.
