Ground Bounce

One customer asked question about whether there is an issue about ground bounce in 300mA I/O output pin. I have checked some materials about ground bounce, this one is good.
So one response is "Our high current drivers have both programmable current limiting and four levels of programmable slew rate, which can mitigate the effects of ground bounce. If you set the slew rate limiting to the slowest setting, you will have no ground bounce issues if the MCU is properly grounded and you are driving a capacitive (non-inductive) load." It is impressive.
