5.2.19 Set Z Axis Magnetic Bias
0xFF
0xAA
0x0d
HXOFFSETL
HXOFFSETH
HXOFFSETL：Set Y axis magnetic bias low byte
HXOFFSETH：Set Z axis magnetic bias high byte
HXOFFSET= (HXOFFSETH <<8) | HXOFFSETL
Note：After setting the magnetic field bias, the output value of the magnetic
field is the sensor measured value minus the zero bias value.
