This section describes the Verbs and Parameters supported by various widgets in the ALC269. If a verb is
not supported by the addressed widget, it will respond with 32 bits of ‘0’.
8.1.
The ‘Get Parameters’ verb is used to get system information and the function capabilities of the HDA
codec. All the parameters are read-only. Refer to section 7.4.1 Command Verb Format, page 22, to get
detailed information about supported parameters.

Get Parameter Command Format
Note: If the parameter ID is not supported, the returned response is 32 bits of ‘0’.
Codec Response Format
Note: The Root Node (NID=00h) supports this parameter.
Codec Response Format
Note: The Root Node (NID=00h in the ALC269) supports this parameter.
For example, Revision ID=00h and Stepping ID=01h indicates the silicon is the A1 version.
