Name	Description	Return Type
MLCompCheck	Checks if the reference of a comparator Pipe Block has been crossed. Returns TRUE if the reference has been crossed.	BOOL
MLCompInit	Initializes a comparator Pipe Block with user-defined settings.	BOOL
MLCompReadRef	Returns the reference position of a comparator block.	None
MLCompReset	Clears the Transition Flag of a comparator Pipe Block.	BOOL
MLCompWriteRef	Sets the reference position of a comparator block.	BOOL

Usage Example of Comparator Functions

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.
