| Data size··········· | 3H (3 bytes) |
| XOver, YOver・・・・・・・・・・・・ | 0: X, Y values (D7 to D0) are valid 1: Data overflow (exceeds 0 to 255) |
|---|---|
| XSign,YSign・・・・・・・・・・・・ | 0: X, Y values (D7 to D0) are positive 1: X, Y values (D7 to D0) are negative |
| XD7〜XD,YD7〜YD0・・・・・・・・・ | Travel amount data (relative value) |
| Middle, Right, Left, Start... | When the button is pressed, it becomes "1" |
| Actual amount of movement | -257 below | -256 | -255 | ... | -2 | -1 | +0 | +1 | +2 | ... | +254 | +255 | +256 that's all |

| Y/X Sign | 1 | 1 | 1 | ... | 1 | 1 | 0 | 0 | 0 | ... | 0 | 0 | 0 |
| Y/X Over | 1 | 0 | 0 | ... | 0 | 0 | 0 | 0 | 0 | ... | 0 | 0 | 1 |
★Note 1: D7 to D0 are not signed. Calculate the amount of movement by paying attention to the changes in each bit of Y/XOver and Y/XSign.
★Note 2: When the Y/XOver bit is set, the amount of movement (D7 to D0) becomes undefined, so be sure to check this bit.
