+          The ADSP-BF52x allows to control input hysteresis for Port F,
+          Port G and Port H and other processor signal inputs.
+          The Schmitt trigger enables can be set only for pin groups.
+          Saying Y will overwrite the default reset or boot loader
+          initialization.
