9.2.4 Data Byte Enable
Microcontrollers have different data byte orientations with regard to the data bus. The
following tables show how the PSD4XX handles the byte enable under different bus
configurations. Even byte refers to locations with address A0 equal to “0”, and odd byte as
locations with A0 equal to “1”.
