3.2. 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 custom-
ers according to their system configuration. Table 9 shows the Pin Widget Configuration Default set-
tings.
