Table 38. ERROR_STATUS: Other Error Status

Addr BIT7 BIT6 BIT5 BIT4 BIT3 BIT2 BIT1 BIT0

0x19 SYNC EDGEERR CH3ERR CH2ERR CH1ERR LEADOFF BATLOW RLDRAIL CMOR

[7] SYNCEDGEERR Digital synchronization error

1: Indicates a digital synchronization error occurred

[6] CH3ERR Channel 3 out-of-range error

1: Indicates an out-of-range error detected on channel 3

[5] CH2ERR Channel 2 out-of-range error

1: Indicates an out-of-range error detected on channel 2

[4 ] CH1ERR Channel 1 out-of-range error

1: Indicates an out-of-range error detected on channel 1

[3] LEADOFF Lead off detected

1: Indicates a lead off was detected on at least one input pin

[2] BATLOW Low battery

1: Indicates the battery voltage has dropped below 2.7 V

[1] RLDRAIL Right leg drive near rail

1: Indicates the right leg drive amplifier output is approaching the supply rails

[0] CMOR Common-mode level out-of-range

1: Indicates the level detected by the common-mode detect block is outside of the input common-

mode range of the amplifiers in the analog front-end

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

[7] RESERVED —

[6] SDM_OR_CH1 Channel 1 sigma-delta modulator over range

1: Indicates an over range detected for channel 1 SDM

[5] SIGN_CH1 Channel 1 instrumentation amplifier output sign

This bit specifies the sign of the output signal of the instrumentation amplifier for channel 1.

0: Positive output of INA larger than negative output

1: Positive output of INA smaller than negative output

[4 ] OUTN_LOW_CH1 Channel 1 instrumentation amplifier negative output near negative rail

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

[3] OUTN_HIGH_CH1 Channel 1 instrumentation amplifier negative output near positive rail

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

[2] OUTP_LOW_CH1 Channel 1 instrumentation amplifier positive output near negative rail

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

[1] OUTP_HIGH_CH1 Channel 1 instrumentation amplifier positive output near positive rail

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

[0] DIF_HIGH_CH1 Channel 1 instrumentation amplifier output out-of-range

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

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