Parallel Port (Peripheral-side)
s s
High-speed, bidirectional, multi-protocol parallel port: s Hardware implementation of all modes of the IEEE STD (Standard) 1284 specification (including automatic negotiation) — Centronics-compatible mode — Reverse Byte mode — Reverse Nibble mode — ECP (extended capabilities port) mode with run-length encoding/decoding — EPP (enhanced parallel port) mode — Up to 2-Mbytes/sec. transfer rate in ECP and EPP modes s 64-byte parallel FIFO with DMA interface — 64-byte FIFO can accommodate up to 4 Kbytes of compressed data with RLE (run-length encoded) compression enabled
