We'd like to drive four separate LEDs from four separate DAI pins on the
ADSP-21489. The Anode of each LED will be tied to +3.3V and the DAI pins
will be pulling the cathode low through a resistor.
We have looked at the "Output Drive Currents" section of the datasheet, but
the reason why we are asking here on the forum is that this may not paint
the whole picture in terms of sustained current through a single pin for
Please let us know if there are any things we need to watch out for here. I
would imagine we would want to sink well under 10mA for each LED.
