41. CCL – Configurable Custom Logic
41.1 Overview
The Configurable Custom Logic (CCL) is a programmable logic peripheral which can be connected to the
device pins, to events, or to other internal peripherals. This allows the user to eliminate logic gates for
simple glue logic functions on the PCB.
Each LookUp Table (LUT) consists of three inputs, a truth table, an optional synchronizer/filter, and an
optional edge detector. Each LUT can generate an output as a user programmable logic expression with
three inputs. Inputs can be individually masked.
The output can be combinatorially generated from the inputs, and can be filtered to remove spikes.
Optional sequential logic can be used. The inputs of the sequential module are individually controlled by
two independent, adjacent LUT (LUT0/LUT1, LUT2/LUT3 etc.) outputs, enabling complex waveform
generation.
