Hi all !
I'm trying to make an aplication using Attiny 25 and I have to use the Reset PIN as a Pin Change Int Source 5 . In the datasheet (section 20.5 ) I have read that the RESET pin has to be held down ( logic 0) to write EEPROM and Flash memory ( ISP ) .
Can I use in system programming if a use Reset pin as a PCINT5 ? If not how can I write program to chip ?
