I wrote a code (asm) which writes data to flash (self-programming). Understanding How Components Fail Wulpi Pdf Converter. Buku Yasin Dan Tahlil Pdf here. It runs on real ATTiny2313 and simulates on ATTiny2313 and ATMega162 without a problem.

My settings for ATMega162: - lock bit byte=0xFF (no restrictions on anything) - enabled OCDEN, JTAGEN, EESAVE, BOR and RC The code below is an example - it does not want to clear allocated data.
