Expand description
Sets electrical characteristics of a pin in a given frequency range
Speed is a selectable bit field that sets electrical characteristics of a pin in a given frequency range. This field provides additional 2-bit slew rate control. These options can either increase the output driver current in the higher frequency range, or reduce the switching noise in the lower frequency range.
The operational frequency on GPIO pads is dependent on slew rate (SRE), speed (SPEED), and supply voltage (OVDD).
See Operating Frequency table in the GPIO block guide in the reference manual for more details.
