Table 6: Measurement Modes
MS1 MS0 Measurement Mode
0
0
Normal measurement configuration (Default). In normal measurement
configuration the device follows normal measurement flow. The positive and
negative pins of the resistive load are left floating and high impedance.
0
1
Positive bias configuration for X, Y, and Z axes. In this configuration, a positive
current is forced across the resistive load for all three axes.
1
0
1
1
Negative bias configuration for X, Y and Z axes. In this configuration, a negative
current is forced across the resistive load for all three axes.
Temperature sensor only. Magnetic sensor will not be enabled during
measurement.
Configuration Register B
The configuration register B for setting the device gain. CRB0 through CRB7 indicate bit locations, with CRB denoting the
bits that are in the configuration register. CRB7 denotes the first bit of the data stream. The number in parenthesis
indicates the default value of that bit. CRB default is 0x20.

Description
Gain Configuration Bits. These bits configure the gain for
the device. The gain configuration is common for all
channels.
CRB4 to CRB0 N/A
These bits must be cleared for correct operation.
