Re: [avr-gcc-list] output current for ATMega128 on output pins

AVR data sheets talk about 25 mA current per pin., but
there is some limitation on the total current drawn.
If you are planing to drive some LEDs (4/5) I think
you can drive them directly from the port pins. You
may consider sinking current to switch the LED ON
rather than on sourcing current.
