dsPIC33EPXXXGS70X/80X FAMILY

21.0 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 21-1 shows an overview

of the module. Figure 21-3 shows the details of the data

source multiplexers and logic input gate connections.
