      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.
