I recently started making ISP for Arduino, but I don´t know if I can use ATMega328P-AU instead of ATMega16U2. On prototype I will be using two ATMega328P-AU. One with ArduinoISP sketch and one with USB Interface firmware. Please help.

@Crossroads,
Is that a USB to TTL SERIAL AND PARALLEL ?(What are P0 - P4 for ?)
