Example of the case where SWAP_2 is on (monotone increase):
The input range of IN_1 is always in CURVE_X. The following shows the input/output graph of the IN_1 values.

Figure A1.5 Example of Curve for IN_2 (SWAP_2 = on)
When SWAP_2 is on, the array elements of CURVE_Y must be configured for a monotone increase or decrease.
(Y1 < Y2 < Y3 < Y4 < Y5 < Y6 or Y6 < Y5 < Y4 < Y3 < Y2 < Y1)
