21 Configurable Logic Cell (CLC)

The Configurable Logic Cell (CLC) module allows the user to specify combinations of signals as inputs to a logic function and to use the logic output to control other peripherals or I/O pins. This provides greater flexibility and potential in embedded designs, since the CLC module can operate outside the limitations of software execution, and supports a vast amount of output designs.

There are four input gates to the selected logic function. These four input gates select from a pool of up to 32 signals that are selected using four data source selection multiplexers. Figure 21-1 shows an overview of the module.

Figure 21-3 shows the details of the data source multiplexers and Figure 21-2 shows the logic input gate connections.
