3.6.4.2 Magnetometer offset
The magnetometer offset can be configured in the following registers,
Table 3-18: Magnetometer Default-Reg settings
Reg Name
Default Reg Value (Bit 0 – Bit 7)
MAG_OFFSET_X_LSB
0x00
MAG_OFFSET_X_MSB
0x00
MAG_OFFSET_Y_LSB
0x00
MAG_OFFSET_Y_MSB
0x00
MAG_OFFSET_Z_LSB
0x00
MAG_OFFSET_Z_MSB
0x00
There are 6 bytes required to configure the magnetometer offset (bytes (2 bytes for each of
the 3 axis X, Y and Z). Configuration will take place only when the user writes the last byte
(i.e., MAG_OFFSET_Z_MSB). Therefore the last byte must be written whenever the user
wants to changes the configuration. The range of the magnetometer offset is +/-6400 in LSB.

3.6.4.3 Gyroscope offset
The gyroscope offset can be configured in the following registers, shown in the table below
Table 3-20: Gyroscope Default Reg-settings
Reg Name
Default Reg Value (Bit 0 – Bit 7)
GYR_OFFSET_X_LSB
0x00
GYR_OFFSET_X_MSB
0x00
GYR_OFFSET_Y_LSB
0x00
GYR_OFFSET_Y_MSB
0x00
GYR_OFFSET_Z_LSB
0x00
GYR_OFFSET_Z_MSB
0x00
There are 6 bytes required to configure the gyroscope offset (bytes (2 bytes for each of the 3
axis X, Y and Z). Configuration will take place only when the user writes the last byte (i.e.,
GYR_OFFSET_Z_MSB). Therefore the last byte must be written whenever the user wants to
changes the configuration. The range of the offset varies based on the dps-range of
gyroscope sensor.
