The Multibus II Peripheral Interface, MPI, is a single chip, "replier only" Parallel System Bus interface device.  This 16-bit integrated CMOS interface component is compliant with the IEEE/ANSI 1296 standard and is compatible with other board products using the 92389 Message Passing Coprocessor.  It supports data transfer in I/O space as defined by the IEEE specification.  The MPI is particularly suited to the design of low-cost, non-intelligent boards.  All interface logic, except for five high current buffer drivers, is incorporated, which simplifies and accelerates I/O board design.  The local interface is designed to provide a simple interface to I/O board components.  The MPI also includes configuration registers which are programmed from the PSB to suit a variety of applications.
