[7] RESERVED —

[6] SDM_OR_CH3 Channel 3 sigma-delta modulator over range

1: Indicates an over range detected for channel 3 SDM

[5] SIGN_CH3 Channel 3 instrumentation amplifier output sign

This bit specifies the sign of the output signal of the instrumentation amplifier for channel 3.

0: Positive output of INA larger than negative output

1: Positive output of INA smaller than negative output

[4 ] OUTN_LOW_CH3 Channel 3 instrumentation amplifier negative output near negative rail

1: Indicates the negative output of the INA is close to the negative rail for channel 3

[3] OUTN_HIGH_CH3 Channel 3 instrumentation amplifier negative output near positive rail

1: Indicates the negative output of the INA is close to the positive rail for channel 3

[2] OUTP_LOW_CH3 Channel 3 instrumentation amplifier positive output near negative rail

1: Indicates the positive output of the INA is close to the negative rail for channel 3

[1] OUTP_HIGH_CH3 Channel 3 instrumentation amplifier positive output near positive rail

1: Indicates the positive output of the INA is close to the positive rail for channel 3

[0] DIF_HIGH_CH3 Channel 3 instrumentation amplifier output out-of-range

1: Indicates the differential output voltage of the INA is out-of-range for channel 3

Note: The clock to digital (internal or external) must be enabled in 0x12[2] for this error register to update.
