Note:
  1. These values are based on simulation. They are not covered by production test limits or characterization.
  2. The I2C pins have faster fall-time in I2C Fast Plus mode (Fm+) and High Speed mode (HS). The fall-time can be in 7 ns range in Fm+ mode, and in 5 ns range in HS mode.
  3. USB pads PA24, PA25 compliant with USB standard in USB mode.
