The Glue Logic Controller (GLOC) contains programmable logic which can be connected to the
device pins. This allows the user to eliminate logic gates for simple glue logic functions on the
PCB.
The GLOC consists of a number of lookup table (LUT) units. Each LUT can generate an output
as a user programmable logic expression with four inputs. Inputs can be individually masked.
The output can be combinatorially generated from the inputs, or filtered to remove spikes.
