"what dioes it matter - you can't read it" When we program any chip programmer first checks signature byte by giving "signature read" status. eg (30H)= 1EH for Atmel products .so what is 30H.Is it the address of ROM ? |

| Yes.I do need | 01/01/70 00:00 | |
| read signature asm code | 01/01/70 00:00 | |
| This is reading a different chip! | 01/01/70 00:00 | |
