11.19 SHAKE_TH: SHAKE THRESHOLD REGISTER
SHAKE_TH has a baseline value of 1.3g plus a threshold, SHAKE_TH. The shake threshold
can range from 0.925g to 1.672g. The value is an 8-bit signed 2’s complement number. The
resolution is approximately 2.9mg/bit. See also Section 9.4 Shake Detection.
Shake Event = ( mag(X) > 1.3g + SHAKE_TH ) or
( mag(Y) > 1.3g + SHAKE_TH ) or
( mag(Z) > 1.3g + SHAKE_TH )
