ESCRIPTION
The OX9162 is a single chip solution for PCI-based parallel
expansion add-in cards, or local bus bridges. It is a single
function PCI device, where function 0 offers either an 8 bit
Local Bus or a bi-directional parallel port.
For legacy applications the PCI resources are arranged so
that the parallel port can be located at standard I/O
addresses.
The efficient 32-bit, 33MHz target-only PCI interface is
compliant with version 2.2 of the PCI Bus Specification and
version 1.0 of PCI Power Management Specification. For
full flexibility, all the default register values can be
overwritten using an optional Microwire
TM
serial EEPROM.
Bridging applications can be realised using the 8-bit pass-
through Local Bus function. The addressable space can be
increased up to 256 bytes for each chip-select region.
The OX9162 alternatively provides an IEEE1284 EPP/ECP
parallel port which fully supports the existing Centronics
interface. The parallel port can be enabled in place of the
Local Bus.
