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.
Reads of this register will read the contents of a “snapshot” register, whose contents
are updated only when the contents of PCA0L are read (see Section 26.1).
