8.31

OFFSET_X_REG_L_M (45h) and OFFSET_X_REG_H_M (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.

8.32

OFFSET_Y_REG_L_M (47h) and OFFSET_Y_REG_H_M (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.

8.33

OFFSET_Z_REG_L_M (49h) and OFFSET_Z_REG_H_M (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.

8.34

WHO_AM_I_M (4Fh)

The identification register is used to identify the device (read-only register).

0(1)

1. This bit must be set to '0' for the correct operation of the device.

MODULE_

0(1)

MODULE_ON

Module processing enable. Default value: 0
