Tool/software:
Someone asked this question previously, but I couldn't find the answer (the discussion digressed into other topics).
The website says the max I/O is +/- 50mA. The datasheet says the I/O current is 50 µA at Vcc=2V and 8mA at 5V. 50mA is pretty far outside that range. Which is correct, the datasheet or the webpage?
