Comparator Functions Examples

When you call the MLCompWriteRef function, the output for MLCompCheck becomes TRUE as soon as the input value reaches the reference.

The same function can also be called for a cyclic input value.

When the THROUGH_ZERO parameter is set to YES, the output for MLCompCheck becomes TRUE as soon as the input value reaches the reference, but not before it has passed through zero.
