offset_y<3:0>
offset_ y<7:0>:
offset value, which is subtracted from the internal filtered and unfiltered y-
axis acceleration data; the offset value is represented with two’s complement
notation, with a mapping of +127 +0.992g, 0 0 g, and -128 -1 g; the
scaling is independent of the selected g-range; the content of the
offset_y<7:0> may be written to the NVM; it is automatically restored from
the NVM after each power-on or softreset; offset_y<7:0> may be written
directly by the user; it is generated automatically after triggering the fast
offset compensation procedure for the y-axis
