ESCRIPTION
The OX12PCI840 is a single chip solution for PCI-based
parallel expansion add-in cards. It is a single function PCI
device.
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.
The OX12PCI840 provides an IEEE1284 EPP/ECP parallel
port which fully supports the existing Centronics interface.
