Supplemental explanation
Follow the steps below to convert AD value entered from touch panel to the corrected coordinates.
1 → 2
(Follow in turn. Execute them during regular operation.)

The effect of correction value declines as the value is going to 255.
(2) If the coordinates are less than or equal to 32 after data expansion;
Coordinates after correction = coordinates after data expansion
÷

32 : Because there are 32 points of coordinates position from the value 0 to 32 (coordinates 0 is not included).
*
The effect of correction value declines as the value is going to 0.
(3) If the coordinates are 33
Coordinates after correction = coordinates after data expansion

Add the correction value at the left corner first. Then, the effect of correction value is increasing as going to right.
