i know that normal IO pins can output 4mA and high current pins can output 8mA, but there is no rating for their current sink.
Anyone knows how much current they can sink?
I guess it must be the same as sourcing capacity.
Fancy asking email@example.com. Please share the information if you get any.
yes, i got reply from ATMEL that the sink capability is the same as sourcing.
And they pointed out some errors at datasheet Rev.G
