Since some of the configuration pins are used for user I/O after programming, a set of logic gates might be necessary to ensure the XCF01S remains disabled following programming. By simply ORing or NORing appropriate signals with the DONE signal, integrity of user I/O signals and signals to the XCF01S can be ensured.
