PIC24FV16KM204 FAMILY
17.0 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 flex-
ibility 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 func-
tion. These four input gates select from a pool of up to
32 signals that are selected using four data source
selection multiplexers. Figure 17-1 shows an overview
of the module. Figure 17-3 shows the details of the data
source multiplexers and logic input gate connections.
