6. PIN CONFIGURATION DEFAULT REGISTER SETTINGS
The configuration default registers are 32-bit registers required for each pin widget. These registers are normally used
by the CODEC driver to determine the configuration of jacks and devices attached to the CODEC. When the CODEC is
powered on, these registers are loaded with the default values provided by IDT for typical system usage, and are
loaded in a way that is compatible with the Microsoft Universal Audio Architecture (UAA) driver. The values can be
overridden by IDT customers according to their system configuration. Table
14 shows the Pin Widget Configuration
Default settings.
