LSM303DLH
By placing the mode register into single-conversion mode (0x01), two data acquisition
cycles are made on each magnetic vector.
The first acquisition is a set pulse followed shortly by measurement data of the external field.
The second acquisition has the offset strap excited in the positive bias mode to create about
a 0.6 gauss self-test field plus the external field. The first acquisition values are subtracted
from the second acquisition, and the net measurement is placed into the data output
registers.
To leave self-test mode, change the MS1 and MS0 bits of the configuration register A back
to 0x00. Also, change the mode register if single-conversion mode is not the intended next
mode of operation.
