RAW
Bit 7
CTRL_REG2 (0x11)
Automatic Magnetic Sensor Reset. Default value: 0.
0: Automatic magnetic sensor resets off.
1: Automatic magnetic sensor resets on.
Similar to Mag_RST, however, the resets occur before each data acquisition.
This bit should normally be explicitly enabled by the user.
Data output correction. Default value: 0. This is a WRITE-ONLY bit.
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.
Magnetic Sensor Reset. 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
(see
When the cycle is finished, value returns to 0.
