This register holds the overall Y
movement data since last polling
was done.
Value is 8 bit 2’s complement.
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.
Allows X to be inverted
Allows Y to be inverted
Replaces X with Y and Y with X
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motion is no longer valid.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
Sets Resolution as CPI:

0x10 - 800 CPI
0x20 - 1600 CPI
0x40 - 3200 CPI
