Absolute max operating voltage for DDR pads with all drive strengths is 1.95 V.
Fast/slow characteristic is selected per GPIO I/O pad (where available) by “slew rate” control. See
Recommended max operating voltage for GPIO in fast mode with all drive strengths is 1.95 V. Absolute maximum is described
