Table 32. CTRL_REG2 Description

AUTO_MRST_EN

Automatic Magnetic Sensor Reset. Default value: 0.

0: Automatic magnetic sensor resets disabled.

1: Automatic magnetic sensor resets enabled.

Similar to Mag_RST, however, the resets occur automatically before each data acquisition.

a WRITE ONLY bit and always reads back as 0.

RAW

Data output correction. Default value: 0.

0: Normal mode: data values are corrected by the user offset register values.

1: Raw mode: data values are not corrected by the user offset register values.

Note: The factory calibration is always applied to the measured data stored in registers 0x01 to 0x06 irrespective of the

setting of the RAW bit.

Mag_RST

Magnetic Sensor Reset (One-Shot). Default value: 0.

0: Reset cycle not active.

1: Reset cycle initiate or Reset cycle busy/active.

When asserted, initiates a magnetic sensor reset cycle that will restore correct operation after exposure to an excessive

magnetic field which exceeds the Full Scale Range (see Table 2) but is less than the Maximum Applied Magnetic Field

(see Table 3).

When the cycle is finished, value returns to 0.
