Ports A, B, C, & E (48-pin package only) support Vref_Out pins for biasing electret cartridge micro-
phones. Settings of 80% AVDD, 50% AVDD, GND, and Hi-Z are supported. Attempting to program a
pin widget control with a reserved or unsupported value will cause the associated Vref_Out pin to
assume a Hi-Z state and the pin widget control Vref_En field will return a value of ‘000’ (Hi-Z) when
read.
Plugs inserted to a jack are detected using SENSE inputs as described in the tables below. Per
ECR15-B, the detection circuit operates when the CODEC is in D0 - D3 and can also operate if both
the CODEC and Controller are in D3 (no bus clock.) Jack detection requires that all supplies (analog
and digital) are active and stable. When AVDD is not present, the value reported in the pin widget is
invalid.
