SHORT_THLD_ FLAG
Short Circuit Threshold Flag = 1 when the absolute value of VOUT is within the absolute
threshold voltage set by the SENDIAG_THLD register.
6
RAILS_FLAG
Rails Flag = 1 when at least one of the inputs is near rail (VA or GND).
5
POR_AFT_LST_RD
Power-on-reset after last read = 1 when there was a power-on-reset event since the last
time the SENDIAG_FLAGS register was read.
[4:3] OFLO_FLAGS
Overflow flags
0x0:
Normal operation
0x1:
The modulator was not overranged, but ADC_DOUT got clamped to 0x7f_ffff (positive
fullscale) or 0x80_0000 (negative full scale)
0x2:
The modulator was over-ranged (VIN > 1.2*VREF/GAIN)
0x3:
The modulator was over-ranged (VIN < -1.2*VREF/GAIN)
[2:0] SAMPLED_CH
Channel Number – the sampled channel for ADC_DOUT and SENDIAG_FLAGS.
