AVR Studio sis gagamitin ko...

Based sa PDF setting LB1 at LB2 to "0" DISABLE na yung READ at WRITE..Tanung ko lang if DISABLE na yung READ at WRITE possible pa kaya magamit yung chip? Baka ayaw na ma ERASE to using serial programming? (AVRISP)

"To clear the Lock bits, a complete Chip Erase is required, which erase the Flash memory."
