I wanted to ask this , because I was getting no information online and I wanted more control over the (hardware ) features of attiny to make as much use of stuff as possible .
so - does doing any of these make an attiny84 unreprogrammable using the arduino uno as ISP?
- playing with timer0
- playing around with USI without resetting the registers to initial values at end of loop
- mistakes while setting up the wdt
- passing a sleep command in assembly after setting registers for a power down
- playing with the ADC registers
please answer this because I want to know them before I do anything to the hardware and by mistake make the chip unreprogrammable. I live in a country where attiny needs to be imported and I can't buy the attinies again and again . sorry if this is a stupid question any tips will be very nice.
