| D | rt5663.txt | 27 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 maximun, 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.
