25.4.3.1 Source Multiplexers

The module has four input source multiplexers. Multiplexer inputs are selected by setting control bits in the CLCxSEL register to define the data source selected through each of the four data selection multiplexers. Each of the four data selection multiplexers feeds one of the four logic function input gates, as shown in Figure 25-3. The module has an internal data bus created from the output of each input source multiplexer (see Figure 25-2). The data bus has both True (T) and Negated (N) versions of each selected input source. Therefore, up to eight signals are available on the internal data bus to connect to the input gates of the logic function.
