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.
