18.6 SENSOR DIAGNOSTIC REGISTERS
SENDIAG_THLD: Sensor Diagnostic Threshold (Address 0x14 - 0x15)
Address Name Register Description
0x14 SENDIAG_THLDH Sensor Diagnostic threshold [15:8]
0x15 SENDIAG_THLDL Sensor Diagnostic threshold [7:0]
SENDIAG_FLAGS: Sensor Diagnostic Flags (Address 0x19 )
Bit Bit Symbol Bit Description
7 SHORT_THLD_ FLAG
Short Circuit Threshold Flag = 1 when the absolute value of VOUT is within the absolute
threshold voltage set by SENDIAG_THLDH and SENDIAG_THLDL.
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.
