Data Byte Enable Reference.
MCUs have differ-
ent data byte orientations. Table 35 to Table 38
show how the PSD4235G2V interprets byte/word
operations in different bus write configurations.
Even-byte refers to locations with address A0
equal to 0, and odd byte as locations with A0 equal
to 1.
Table 35. 16-Bit Data Bus with BHE
MCU Bus Interface Examples.
Figure 21 to Fig-
ure 26 show examples of the basic connections
between the PSD4235G2V and some popular
MCUs. The PSD4235G2V Control input pins are
labeled as to the MCU function for which they are
configured. The MCU bus interface is specified us-
ing PSDsoft Express. The Voltage Stand-by (VST-
BY, PE6) line should be held at Ground if not in
use.
