Figure 12. An Example of a Typical Non-Multiplexed Bus Interface,
8 or 16-Bit Data Bus
PSD7XX Interface To a Non-Multiplexed Bus
Figure 12 shows an example of a system using a microcontroller with a non-multiplexed
bus and a PSD7XX. The address bus is connected to the ADIO Port, and the data bus is
connected to Port A (D[7:0]) and to Ports B (D[15:8], 16-bit data bus only). The data Ports
are in tri-state mode when the PSD7XX is not accessed by the microcontroller. Should the
system address bus exceed sixteen bits, Port A, B, or C may be used as additional address
inputs.
