The UC3C Datasheet doesn't provide a clear explanation about "drive strength", how it behaves and the side effects in projects. After fabricating my board I realized I placed a LED on a x1 strength pin (AVR32UC3C2512C pin PB00) and I calculate a 23mA current ((5V[input] - 1.5V[LED drop])/150ohm).
In table 40-6 there is a tip that x1 handles 3.5mA, so what happens if I turn this LED on? Will the LED drain more current than the pin can handle and burn the MCU or will the MCU limit the current to 3.5mA? Or does it means something entire different?
