I seem to recall it is per pin, but up to a maximum total of <x>, for which I cannot remember the value for <x>. Perhaps 60mA.

#72252 Something to consider. The voltage at the pin is affected by the current. A high with heavy loading will not have as much voltage. And when sinking current the voltage will not be as low.
