Cursor Mode Controls

Bank Register Name Addr Bits

Default

Value R/W Description

0 R_CursorUseTop 0x32 0 0x01 R/W 1: Enable cursor center function

If enabled, the cursor object information will involve

R_CursorTopRatio for the calculation

Refer to R_CursorTopRatio

0 R_CursorUseBGModel 0x32 1 0x00 R/W 1: If cursor center function is enabled, the cursor object

information will involve background model for the

calculation

0 R_CursorInvertY 0x32 2 0x00 R/W 1: Horizontal cursor center inverse

0 R_CursorInvertX 0x32 3 0x01 R/W 1: Vertical cursor center inverse

0 R_ CursorTopRatio 0x32 5:4 0x02 R/W Use the  rst R_CursorTopRatio / 8 part of the object to

calculate center

Example :

If the original object size is 100, the cursor object size

will be 25 at R_CursorTopRatio = 2, The cursor center

will move from the center of the object to the upper

1/4 part

0 R_PositionFilterStartSizeTh 0x33 7:0 0x01 R/W Low byte

As object size > R_PositionFilterStartSizeTh, use the

object information after IIR  lter for cursor

0 R_PositionFilterStartSizeTh 0x34 0 0x00 R/W High byte

As object size > R_PositionFilterStartSizeTh, use the

object information after IIR  lter for cursor

0 R_ProcessFilterStartSizeTh 0x35 7:0 0x01 R/W Low byte

As object size > R_ProcessFilterStartSizeTh, use the

object information after IIR  lter for gesture detection

0 R_PositionFilterStartSizeTh 0x36 0 0x00 R/W High byte

As object size > R_ProcessFilterStartSizeTh, use the

object information after IIR  lter for gesture detection

0 R_CursorClampLeft 0x37 4:0 0x09 R/W Minimum cursor horizontal center value, if data <

R_CursorClampLeft, clamp at 0 else, clamp at data –

(R_CursorClampLeft << R_PositionResolution)

Example :

R_CursorClampLeft = 9,

R_CursorClampRight = 21,

R_PositionResolution = 0,

X = 5 ≥ X' = 0

X = 10 ≥ X' = 10 – 9 = 1

X = 25 ≥ X' = 20 – 1 – 9 = 10

Example :

R_CursorInvertY = 0,

R_CursorClampRight = 20,

R_PositionResolution = 2,

Y = 50, set R_CursorInvertY = 1,

R_CursorClampRight = 20,

R_PositionResolution = 2, ≥ Y' = 20 × (2

) – 50 = 30

0 R_CursorClampRight 0x38 4:0 0x15 R/W Maximum cursor horizontal center value,

if data is > R_CursorClampRight, clamp at –1

0 R_CursorClampUp 0x39 4:0 0x0A R/W Minimum cursor vertical center value, if data < R_Cur-

sorClampUp, clamp at 0 else, clamp at data – (R_Cur-

sorClampUp << R_PositionResolution)

0 R_CursorClampDown 0x3A 4:0 0x12 R/W Maximum cursor vertical center value,

if data is > R_CursorClampDown, clamp at –1

0 CursorClampCenterX 0x3B 7:0 0x00 R Low byte of clamping center X

0 CursorClampCenterX 0x3C 3:0 0x7D R High byte of clamping center X

size > R_Cursor_ObjectSizeTh, trigger cursor has

object interrupt

0 R_PositionResolution 0x8C 2:0 0x07 R/W Cursor mode object resolution,

Example :

(x,y) = (1000,1000) at R_PositionResolution = 7,

=> real (x',y') = (1000 / 2

,1000/2

) = (7.8125,7.8125)

which maps to 30×30 scale
