Selects Interface Control Mode
0 = MODE pin selects 2-wire mode when
low and 3-wire mode when high.
1 = Interface operates in 3-wire mode
regardless of the MODE pin. MODE can be
an input or output under the control of the
GPIO control register.
Jack Detect Switch Enable
0 = Jack Detect disabled
1 = Jack Detect enabled
Jack Detect Switch Polarity
0 = Jack Detect active high
1 = Jack Detect active low
GPIO Output Polarity Invert
0 = Non inverted
1 = Inverted
GPIO Pin Function Select:
000 = Jack detect input
001 = Reserved
010 = Temperature ok
011 = Debounced jack detect output
100 = SYSCLK output
101 = FLL lock
110 = Logic 0
111 = Logic 1
Jack Detect Input Select
000 = ADCLRC/GPIO used for jack detect
001 = CSB/GPIO used for jack detect
010 = LINPUT3/JD used for jack detect
011 = RINPUT3/JD used for jack detect
100 = MODE/GPIO used for jack detect
101 to 111 Reserved
Temperature Sensor Enable
0 = Temperature sensor disabled
1 = Temperature sensor enabled
Microphone Bias Voltage Control
0 = 0.9 * AVDD
1 = 0.65 * AVDD
Connect LINPUT1 to inverting input of Left
Input PGA
0 = LINPUT1 not connected to PGA
1 = LINPUT1 connected to PGA
Connect LINPUT2 to non-inverting input of
Left Input PGA
0 = LINPUT2 not connected to PGA
1 = LINPUT2 connected to PGA
Connect LINPUT3 to non-inverting input of
Left Input PGA
0 = LINPUT3 not connected to PGA
1 = LINPUT3 connected to PGA
Connect RINPUT1 to inverting input of
Right Input PGA
0 = RINPUT1 not connected to PGA
1 = RINPUT1 connected to PGA
