Hi ,

I enable write protection for Sector 8 , which set my option byte to 0x0EFFAAED as i can read from debugger  ( IAR ). but as soon as i restart my debugger again i found read protection set to level 1 . i.e value of option byte turns to 0x0EFFFFED.

I am not touching RDP byte anywhere from my code.
No power fluctutaion and no ESD discharge .

Is there any other way that RDP turn to level 1 without explictly writing on RDP option byte ??
