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.
8.36
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.
8.37
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.
8.38
WHO_AM_I_M (4Fh)
The identification register is used to identify the device (read-only register).
