I've found the following schematic:
Which after a lot of datasheet reading I mostly understand.
The main thing I don't understand, however, is what's going on with the RESET pin. First of all, I understand that the RESET pin is active-low. In this case, why is it pulled high to +5V? Surely I wouldn't want the CPU to reset. I assume the answer to this part is something to do with resetting on boot.
My main question is why there's a capacitor from RESET to (what seems to be) ground.
Is that even ground? If so, why is there a capacitor before it? If not, what is it, and what does it do?
