Restoring the Fuse-bits configuration of ATtiny13, ATtiny25/45/85 (HVSP)
Sometimes, when developing devices on 8- and 14-pin AVR microcontrollers, it is necessary to use the Reset pin as an input/output line. This can be done by setting the appropriate Fuse-bit configuration. But after these actions, access to the microcontroller for in-circuit programming is lost, because we disable the Reset line. We will consider a …
