Data Byte Enable Reference
Microcontrollers have different data byte orientations. The following tables show how
the PSD6XXE1 interprets byte/word operation in different write bus configurations.
Even-byte refers to locations with address A0 equal to zero and odd byte as locations
with A0 equal to one.
