m_raw

Magnetic measurement RAW mode enable:
0: Values stored in the M_OFF_X/Y/Z registers are applied to the magnetic sample data. This bit must be cleared 
in order for the automatic hard-iron compensation function to have any effect. 
1: Values stored in M_OFF_X/Y/Z are not applied to the magnetic sample data; automatic hard-iron compensation 
function does not have any effect on the output data.

m_aslp_os[2:0]

Defines magnetometer OSR in Auto-Sleep mode. See 

.

m_ths_xyz_update

This control bit defines which reference values are updated when the magnetic threshold event detection function 
triggers.
0:

 

X, Y and Z reference values are all updated when the function triggers on any of the X, Y, or Z axes.

1

: 

Only the reference value for the axis that triggered the detection event is updated.

m_st_z

Enables Z-axis magnetic self-test function when set.

m_st_xy[1:0]

Enables both X and Y axes magnetic self-test function simultaneously when set to a value greater than 0b00. 
X and Y magnetic self-test is disabled when this field is set to 2'b00
