OX9160

      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.The local bus of OX9160 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 of OX9160 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 of OX9160 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 MicrowireTM serial EEPROM.
