what really happens during port high and low in startkit?

Post by georgel2004 »

In the GPIO ports,

1. when the code drives the port high 1 and low 0, what is really happening?

2. What is the voltage and current during high and low?

3. Also what is the default state of the ports, are they at high or low state?

Is there any document that clearly explains this.

Thanks
