Table 8.
Add
Reg [#0x22]: Y_motion
Bits
Name
0x22
[7:0] Y_motion
R/W
Default
Description
This register holds the overall Y
movement data since last polling
RO
0000_0000 was done.
Value is 8 bit 2’s complement.
Table 9.
Add
Reg [#0x23] Overflow / No motion
Bits
Name
R/W
[0] X_overflow
0x23
[1] Y_overflow
RO
[3] No motion
Default
Description
This register records if the X -
motion integrator has reached its
limit.
This register records if the Y -
motion integrator has reached its
limit.
Flag is set when there has been
no event at the moment the host
is polling for movement.

Table 11. Reg [#0x29]: Minimum Features
Add
Bits
Name
R/W
0x29
[7:0] Min_features[13:6]
R/W
Default
0000_0000
Description
This register represents the
feature threshold below which
motion is no longer valid. This is
linked to the value reported in
registers 0x31 & 0x32.
If Features [13:6] (reg0x31/32) <
Min features (0x29), then X/Y
motion = 0
