The problem is with the programmer.They second bit is always stuck at 1 for every byte i right ie for 00h it writes 02h,for 71h it write 73h

Ah, now I see.

Seems to be a hardware malfunction. Search for any short circuit on PCB, cables, sockets, etc. May be exchange of according chips will help.

By the way, have you soldered PCB correctly? Sometimes, when soldering too hot and too long, flux becomes carbonized, and then will become a conducting material. I once had to face this problem in combination with a SRAM. So, cleaning of PCB will help.

Good luck,
