If bit 13 of C is set to 1, the graph will be reflected from left to right, as shown
in the following diagram.
The following example demonstrates the construction of a linear approxima-
tion with 12 line segments. The block of data is continuous, as it must be, from
DM 0000 to DM 0026 (C to C + (2
× 12 + 2)). The input data is taken from IR
010, and the result is output to IR 011.
In this case, the input data word, IR 010, contains #0014, and f(0014) = #0726
is output to R, IR 011.
