Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | CH1_INTYP | RW | 0h | Channel 1 input type.
0d = Microphone input 1d = Line input |
6-5 | CH1_INSRC[1:0] | RW | 0h | Channel 1 input configuration.
0d = Analog differential input 1d = Analog single-ended input 2d = Reserved 3d = Reserved |
4 | CH1_DC | RW | 1h | Channel 1 input coupling.
0d = AC-coupled input 1d = DC-coupled input |
3 | CH1_MIC_IN_RANGE | RW | 0h | Channel 1 microphone input range.
0d = Low swing mode; Differential input AC signal full-scale of 2-VRMS supported provided DC differential common mode voltage IN1P - IN1M < 4.2 V. Single-ended AC signal 1-VRMS supported provided DC common mode voltage is < 2.1 V. 1d = High swing mode; Differential Input IN1P-IN1M peak voltage up to 14.14 V or single ended 7.07 V supported. User rquired to adjust the channel gain and digital volume control based on the max signal level used in system. |
2-1 | CH1_PGA_CFG[1:0] | RW | 0h | Channel 1 CMRR Configuration.
0d = High SNR performance mode 1d = Reserved 2d = High CMRR performance mode 3d = Reserved |
0 | CH1_AGCEN | RW | 0h | Channel 1 automatic gain controller (AGC) setting.
0d = AGC disabled 1d = AGC enabled based on the configuration of bit 3 in register 108 (P0_R108); This must be used only with AC-coupled input |
