Description
This bit is the auto-range detection output for DAC group D. This
bit is set to 1 when AV_SSD < AV_SSTH (–10- to 0-V output range),
and 0 when A_VSSD > AV_SSTH (0- to 5-V output range).
This bit is the auto-range detection output for DAC group C. This
bit is set to 1 when AV_SSC < AV_SSTH (–10- to 0-V output range),
and 0 when AV_SSC > AV_SSTH (0- to 5-V output range).
This bit is the auto-range detection output for DAC group B. This
bit is set to 1 when AV_SSB < AV_SSTH (–10- to 0-V output range),
and 0 when AV_SSB > AV_SSTH (0- to 5-V output range).
This bit is the auto-range detection output for DAC group A. This
bit is set to 1 when AV_EE < AV_SSTH (–10- to 0-V output range),
and 0 when AV_EE > AV_SSTH (0- to 5-V output range).
ADC Idle indicator.

Auto mode: 1 by default; goes to 0 once the ADC is
triggered and is running. Remains 0 until ADC is stopped,
then ADC_IDLE returns to 1.
Direct mode: 1 by default; goes to 0 once the ADC is
triggered and direct conversions are running and returns to
1 when direct mode conversions are completed.
Reserved for factory use
Global alarm bit.
This bit is the OR function or all individual alarm bits of the
status register. This bit is set to 1 when any alarm condition
occurs and remains set until the status register is read. This bit
is cleared after reading the Status Register.
ADC Data available flag bit. Direct mode only. Always cleared in
Auto mode.
0: ADC conversion is in progress or ADC is in Auto mode
1: ADC conversions are complete and new data is available
