8.1

OFFSET_X_REG_L (45h) and OFFSET_X_REG_H (46h)

These registers comprise a 16-bit register and represent X hard-iron offset in order to

compensate environmental effects (data in two’s complement). These values act on the

magnetic output data value in order to delete the environmental offset.

8.2

OFFSET_Y_REG_L (47h) and OFFSET_Y_REG_H (48h)

These registers comprise a 16-bit register and represent Y hard-iron offset in order to

compensate environmental effects (data in two’s complement). These values act on the

magnetic output data value in order to delete the environmental offset.

8.3

OFFSET_Z_REG_L (49h) and OFFSET_Z_REG_H (4Ah)

These registers comprise a 16-bit register and represent Z hard-iron offset in order to

compensate environmental effects (data in two’s complement). These values act on the

magnetic output data value in order to delete the environmental offset.

8.4

WHO_AM_I (4Fh)

The identification register is used to identify the device.
