All power management state changes in widgets are driven by software. Table 17 indicates the definitions

of power states.

In the ALC262-VD, the Audio Function (NID=01h), input converter, output converter, and each pin

widget supports power control. Software may have various power states dependent on system

configuration. Table 17 indicates those Nodes that support power management. To simplify power

control, software can configure whole codec power states using only the Audio Function (NID=01h).

Output converters (DACs) and input converters (ADCs) have no individual power control to supply

fine-Grained power control.
