The Initial Key for Plug and Play (PnP)
The Plug and Play logical is quiescent on power up and must
be enabled by software. This accomplished with a predefined
sequence of indices (32 I/O writes) to the Address port. This
sequence is called the Initiation Key. The write sequence is
decoded by DM9008. 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.
