If set, this bit sets MOTION pin
HIGH, otherwise sets it low.
This bit reflects the actual value
of the signal on the
POWER_DOWN pin.
0: MOTION is high to indicate
that motion has been received
1: MOTION is low to indicate
that motion has been received
0: MOTION output is CMOS
1.8V
1: MOTION output is OpenDrain
5V tolerant.
This bit clears both X & Y
accumulators from the current
reported value.
In case of severe overflows
generated by great motion
values, several poll motions may
be needed to completely flush
out motion from the integrator.
For X/Y motion reads via I
it is recommended that this bit is
set to 1 at power-up by the
master.
This way X & Y motion registers
are actually cleared
automatically after their
respective read.
X/Y motion registers should be
read in a multiple read
sequence.
This register holds the overall X
movement data since last polling
was done.
Value is 8 bit 2’s complement.
