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 signalling 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
SPKVOL L/R step size to .75dB. Added additional verb for updating speaker L and R volume at the

section wording related to D3Cold entry. Added description text for High pass filter feature.
Corrected Sense A/B description and table.
Corrected front page bullet for BTL voltage and corrected functional block diagram for the BTL filter
type.
Corrected Left vs Right channel for the EQ coefficients to match silicon. Updated electrical
characteristics for typical values. Removed Preliminary. Removed comments related to ZA and ZB
silicon since they were non-production. Added PVDD value for the digital maximum supply voltage
and footnote to the GPIO characteristics for the Input Low and High Voltage.
Corrections for 022FB0 / 0227B0 to 022FB6 / 0227B6 as they are not reachable via NID22 but must
be accessed through the Port Nodes. UpdatedNID22 registers with reset information, which is
