The adding mode is set if the chosen start count value SC is lower
than preset values P1 and P2. The subtracting mode is set if the
chosen start count value SC is greater than preset values P1 and P2.
The subtracting mode is impractical in operating modes 2 (parallel
comparison) and 3 (self-adjusting preset).
