CL-CD1284 — IEEE 1284-Compatible Parallel Interface Controller

Hardware implementation of all modes of

the IEEE STD (Standard) 1284

specification (including automatic

negotiation)

64-byte parallel FIFO with DMA interface

— Centronics -compatible mode

— Reverse Byte mode

— Reverse Nibble mode

— ECP (extended capabilities port) mode

— EPP (enhanced parallel port) mode

— Up to 2-Mbytes/sec. transfer rate in ECP

with run-length encoding/decoding

and EPP modes

Two Serial UARTs

Serial channel asynchronous protocol

support to 115.2 kbps (register-set-

compatible and functionally identical to

CD1400)

— Twelve-byte FIFOs for each transmitter

— Improved interrupt schemes: Good

— User-programmable and automatic flow

— Special character recognition and

— Special character processing,

— Six modem control signals per channel

and receiver with programmable

threshold for receive FIFO interrupt

generation

particularly useful for UNIX

environments, optionally handled

automatically by the serial channels.
