Description

DRDY

Conversion result ready flag.

This bit flags if a new conversion result is ready. This bit is reset when conversion

data are read.

0 : No new conversion result available (default)

1 : New conversion result ready

DCNT

R/W

Data counter enable.

The bit enables the conversion data counter.

0 : Conversion counter disabled (default)

1 : Conversion counter enabled

5:4

CRC[1:0]

R/W

Data integrity check enable.

These bits enable and select the data integrity checks.

00 : Disabled (default)

01 : Inverted data output enabled

10 : CRC16 enabled

11 : Reserved

BCS

R/W

Burn-out current sources.

This bit controls the 10-µA, burn-out current sources. The burn-out current

sources can be used to detect sensor faults such as wire breaks and shorted

sensors.

0 : Current sources off (default)

1 : Current sources on

2:0

IDAC[2:0]

R/W

IDAC current setting.

These bits set the current for both IDAC1 and IDAC2 excitation current sources.

000 : Off (default)

001 : 10 µA

010 : 50 µA

011 : 100 µA

100 : 250 µA

101 : 500 µA

110 : 1000 µA

111 : 1500 µA
