Drt5663.txt27 The matrix row number of the impedance sensing table.
28 If the value is 0, it means the impedance sensing is not supported.
30 The matrix rows of the impedance sensing table are consisted by impedance
31 minimum, impedance maximum, volume, DC offset w/o and w/ mic of each L and
35 The first and second column are defined for the impedance range. If the
36 detected impedance value is in the range, then the volume value of the
41 impedance in the impedance sensing function.
Dcs43130.txt29 Boolean, define to enable headphone DC impedance measurement.
32 Boolean, define to enable headphone AC impedance measurement.
33 DC impedance must also be enabled for AC impedance measurement.
36 Define 2 DC impedance thresholds in ohms for HP output control.
40 Define the frequencies at which to measure HP AC impedance.
