PSD Interface to a Non-Multiplexed 8-Bit Bus
Figure
20
shows an example of a system using a
MCU with an 8-bit non-multiplexed bus and a
PSD. The address bus is connected to the ADIO
Port, and the data bus is connected to Port A. Port
A is in tri-state mode when the PSD is not access-
ed by the MCU. Should the system address bus
exceed sixteen bits, Ports B, C, or D may be used
for additional address inputs.
Data Byte Enable Reference
MCUs have different data byte orientations. Table
17
shows how the PSD interprets byte/word oper-
ations 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.’
MCU Bus Interface Examples
Figure
21
through
25
show examples of the basic
connections between the PSD and some popular
MCUs. The PSD Control input pins are labeled as
to the MCU function for which they are configured.
The MCU bus interface is specified using the PS-
Dsoft Express Configuration.
