Description of Change
initial release
updated 40QFN package drawing for different DAP size.
Aux mode section added, corrected package code in orderable part numbers
Added changes for YA silicon revision (ZA/ZB prior settings referenced)
AFG EAPD bit added for PortE Headphone control. AFG ComJack bits added to select debounce
time. Removed SCS support. Updated 40QFN package diagram. Updated conditions of
performance characteristics, added HDA signaling voltage to condition for power measurements.
Default changed on BTL/HD_Mode from 0 to 1.Corrected Combo Jack diagram.Added Pin
Configuration Default Settings.
Updated LDO Level Control values. Corrected step size and thermal trip in BTL section. Updated

characteristics for typical values. Removed Preliminary. Removed comments related to ZA and ZB
silicon since they were non-production. Added WB silicon widget items: ComboJackTiming in the
AFG and ScStableTimeSel added to AFG AnaBTL. Added PVDD value for the digital maximum
supply voltage and footnote to the GPIO characteristics for the Input Low and High Voltage.
Added feature bullet and description section for microphone input mute which is available only on
silicon revisions WB and beyond.
Corrections for 022FB0 / 0227B0 to 022FB6 / 0227B6 as they are not reachable via NID22 but must
