This document describes how to use the features of the ATV750 and ATV750B in the ABEL and CUPL high level description languages. The ATV750 and ATV750B are easy upgrades from a 22V10, offering twice the logic density and more flexibility in the same footprint. Both devices have 20 registers and individual clock and AR product terms for each register. Each I/O pin has a programmable polarity control and an individual output enable product term. Independent feedback paths from each register allow all of the registers to be buried without wasting the I/O pins. For the ATV750B, the registers can also be configured as D- or T-type and the clock can be selected as either a synchronous clock pin or a clock product term.
