ESCRIPTION
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 throught 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
signalling.
Alternatively the local bus can be disabled in favour 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.
