PCA Counter/Timer Low Byte.
Function
The PCA0L register holds the low byte (LSB) of the 16-bit PCA Counter/Timer.
Note:
When the WDTE bit is set to 1, the PCA0L register cannot be modified by software. To change the contents of
the PCA0L register, the Watchdog Timer must first be disabled.

PCA0[15:8]
PCA Counter/Timer High Byte.
Function
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 28.1).
Note:
When the WDTE bit is set to 1, the PCA0H register cannot be modified by software. To change the contents of
the PCA0H register, the Watchdog Timer must first be disabled.
