The OX9160 is a low-cost, general purpose PCI bridge
solution designed to ease the migration to PCI of
parallel port cards and instrumentation devices. It is
configurable to provide either a Local bus interface or a
bi-directional parallel port.
Using the local bus function, legacy devices can be
easily accessed through the target PCI interface, which
is compliant with version 2.2 of the PCI Bus
Specification and version 1.0 of PCI Power
Management Specification. All reads and writes are
completed with a minimum of PCI wait states, which
ensures lower PCI bus occupancy than most similar
PCI bridge solutions.
The local bus can be configured to operate with either
8- or 32-bit data, using either Intel x86 style or Motorola
style signaling.
Alternatively the local bus can be disabled in favor of an
integrated IEEE 1284 EPP parallel port. The parallel
port is an IEEE 1284-compliant host interface, which
supports SPP, PS2 (bidirectional) and EPP modes.
The local Bus function is extremely flexible, allowing the
designer to customize the addressable space, divide it
into chip-select regions, access devices via I/O or
memory space mapping, and adjust the timings of all
operations. The default register values have been
selected to support many standard peripheral chips
such as I/O controllers and other ISA-type devices,
however all such parameters can be overwritten using
an optional Microwire
TM
serial EEPROM.
