PSD Interface to a Non-Multiplexed 8-Bit Bus
Figure
22
shows an example of a system using a
microcontroller 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
accessed by the microcontroller. Should the sys-
tem address bus exceed sixteen bits, Ports B, C,
or D may be used for additional address inputs.
