|---|---|---|---|---|
| 7 | PD_MBIAS_FAULT1 | RW | 0h | Powerdown configuration of MICBIAS fault 1
0d = No powerdown when MICBIAS fault detected 1d = MICBIAS and all ADC channels gets powerdown when low current fault occurs and P0_R40, PD_ON_FLT_CFG = 1d 1d = MICBIAS and all ADC channels gets powerdown when high current fault occurs and P0_R40, PD_ON_FLT_CFG = 2d |
| 6 | PD_MBIAS_FAULT2 | RW | 0h | Powerdown configuration of MICBIAS fault 2
0d = No powerdown when MICBIAS fault detected 1d = MICBIAS and all ADC channels gets powerdown when over voltage fault occurs and P0_R40, PD_ON_FLT_CFG = 1d 1d = MICBIAS and all ADC channels gets powerdown when low current fault occurs and P0_R40, PD_ON_FLT_CFG = 2d |
| 5 | PD_MBIAS_FAULT3 | RW | 0h | Powerdown configuration of MICBIAS fault 3
0d = No powerdown when MICBIAS fault detected 1d = MICBIAS and all ADC channels gets powerdown when over temperature fault occurs and P0_R40, PD_ON_FLT_CFG = 1d 1d = MICBIAS and all ADC channels gets powerdown when over voltage fault occurs and P0_R40, PD_ON_FLT_CFG = 2d |
| 4 | PD_MBIAS_FAULT4 | RW | 1h | Powerdown configuration of MICBIAS fault 4
0d = No powerdown when MICBIAS fault detected 1d = MICBIAS and all ADC channels gets powerdown when high current fault occurs and P0_R40, PD_ON_FLT_CFG = 1d 1d = MICBIAS and all ADC channels gets powerdown when over temperature fault occurs and P0_R40, PD_ON_FLT_CFG = 2d. It is recommended to use this setting to protect chip from over temperature fault. |
