Add
:
Reg [#0x05] - IO_Control
Bits
Name
[0] Motion
[1] Power_Down
0x05
[2] Motion PIN polarity
[3] Motion PIN OD mode
Operation
R/W
Default
Description
R/W
0
If set, this bit sets MOTION pin
HIGH, otherwise sets it low.
This bit reflects the actual value
RO
of the signal on the
POWER_DOWN pin.
0: MOTION is high to indicate
that motion has been received
R/W
0
1: MOTION is low to indicate
that motion has been received
0: MOTION output is CMOS
1.8V
R/W
0
1: MOTION output is OpenDrain
5V tolerant.

Add
Reg [#0x20]: Clear_Motion
Bits
Name
[0]
Empties Motion
accumulators
0x20
Enable Automatic motion
[1] integrators to empty
automatically when reading
Table 7.
Add
Reg [#0x21]: X_motion
Bits
Name
0x21
[7:0] X_motion
R/W
Default
Description
This bit clears both X & Y
accumulators from the current
reported value.
0
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 I2C i/f,
R/W
it is recommended that this bit is
set to 1 at power-up by the
master.
This way X & Y motion registers
0
are actually cleared
automatically after their
respective read.
X/Y motion registers should be
read in a multiple read
sequence.
R/W
Default
Description
This register holds the overall X
movement data since last polling
RO
0000_0000 was done.
Value is 8 bit 2’s complement.
