6.7 Hint 7- Using Slew Rate Control

The ATF15XX/ATF1500 supports per‑macrocell output slew rate control, allowing designers to tailor output switching characteristics to system timing requirements. Slower slew rates can reduce system noise and are the default setting applied by the fitter. If specific outputs must interface with higher‑speed devices or if overall performance optimization is required, individual macrocell outputs can be configured to use a fast slew rate.
