What to do with PE0 and PE1 programing pins? Do i treat them like any other unconnected pin or is there something special I do with them? Im assuming that since the ISP mode is only enabled when the chip is in a reset state... |

The PEN pin I want to make sure I understand the PEN pin's function before I end up pulling it up with a resistor. The PEN pin is another way to force the Atmega chip into ISP mode. If CLK... |
