24.1 CLC Setup
Programming the CLC module is performed by configuring the four stages in the logic
            signal flow. The four stages are:
        - Data selection
 - Data gating
 - Logic function selection
 - Output polarity
 
Each stage is set up at run time by writing to the corresponding CLC Special Function Registers. This has the added advantage of permitting logic reconfiguration on-the-fly during program execution.
