What is the purpose or advantage of using Slew Rate controlled output capability for GPIOs?

  • \$\begingroup\$ Slew rate control limits the production of high frequency components in a transition and reduces the potential 'noise' produced by any given circuit. This becomes ever more important as PCB track length get longer or you transition in wires to go offboard. \$\endgroup\$ – Jack Creasey Oct 30 '17 at 16:23
