The 4 points on the screen, P1 (X1,Y1), P2 (X2,Y2), P3 (X3,Y3),
P4 (X4,Y4) are the coordinate values (voltage values) actually
read by touch adjustment.
The points shown on the adjustment screen have 2 dots, one for
X and one for Y coordinate.
In normal mode touch adjustment, P2 and P4 coordinates are ac-
quired. In test mode touch adjustment, coordinates of P1 to P4
are acquired (The reference point is lower left, whose coordinate
value shall be (1,1).
