PCA0H PCA Counter/Timer High Byte.
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.
Note: When the WDTE bit is set to 1, the PCA0H register cannot be modified by firmware. To change the contents of the
PCA0H register, the Watchdog Timer must first be disabled.
