Slave_ dataw[7:0]

Data to be written into the slave device according to the rw_0 bit in

SLV0_ADD (30h) register or address to be read in source mode.

Default value: 00000000

SM_THS

SM_THS_[7:0]

These bits define the threshold value which corresponds to the number of

steps to be performed by the user upon a change of location before the sig-

nificant motion interrupt is generated.

It is expressed as an 8-bit unsigned value. The default value of this field is

equal to 6 (= 00000110b).
