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. http://www.ultracad.com/articles/g_bounce.pdf
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.
