Figure 16. An Example of a Typical 8-bit Multiplexed Bus Interface
PSD Interface to a Non-Multiplexed 8-Bit Bus.
Figure 17 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.
