Realtek Full-Duplex Ethernet Controller with Plug and Play Function (RealPNP)

Realtek Semiconductor 

SPECIFICATION

RTL8019AS

6.2. Plug and Play

6.2.1. Initiation Key

The Plug and Play logic is quiescent on power up and must be enabled by software. This is done

by a predefined series of writes (32 I/O writes) to the ADDRESS port, which is called the

initiation key. The write sequence is decoded by RTL8019AS. If the proper series of I/O writes is

detected, then the Plug and Play auto-configuration ports are enabled. The write sequence will be

reset and must be issued from the beginning if any data mismatch occurs. The exact sequence for

the initiation key is listed below in hexadecimal notation.
