Hi, I'm trying to figure out whether I can use the !reset pin on an attiny45 and still have the ability to reprogram it, I figured out I can set a fuse to use it as a data pin, but then it's bricked as far as reprogramming. I am using the arduino as isp programmer right now, but I got avr studio and an avr ice programmer, I'm sticking with the arduino ide for this project just to get it out the door but am planning on moving over to avr studio for future projects.

Hi, the reset pin is either a MC reset pin AND programming pin OR a port data pin. So without changing any fuses it is by default able to reset the MC in normal operation.
