Description of Change
Initial release
Added widget details.Integrated addendum sections into datasheet.
Removed low voltage part number, as not needed as the DVD_IO pin dynamically selects low
voltage (1.5V) or normal (3.3V) HDA bus signaling based on what voltage is on the pin
YA revision and beyond
Corrected Mic Boost Voltages in
Characteristics (PRELIMINARY)”
Updated to include Aux mode

• BTL amp gain settings added to
• Corrected tables in
• Widget Changes in AFG (NID = 01h)
• AFGEAPD changed to have separate control bits for BTL, HP-A and HP-B
• AFGAnaPort Verb changed to remove the GSMark control, and to provide Ports A and B
• AFGAnaBeep Verb changed to add more flexible modes of operation
• AFGAnaBTL Verb changed to add MaxVol field and remove +6db control. Other fields
• AFGAnaCapless Verb changed for new charge pump clock controls, as well as new test
with one power down control each, as opposed to each having a HP power down and a lin-
eout power down
shifted a bit to maintain logical grouping
