Project Bureau — ATF1502AS Pin Configuration

Project Bureau aims at documenting the bitstream format of Microchip ATF15xx CPLDs. The documentation for ATF1502AS is complete. See more in the repository.

Most pins are configured through the associated macrocells. This page describes configuration of dedicated inputs and pins configured to have a special function.
