I am working with P89C51RD2(PLCC package). I purchase a new IC. Start to program using flash magic. When I press Start, it shows a message "Security bit 1 is set".
And from ISP->ReadSecurity, I come to know that Security bits 1, 2 and 3 all are set.
I want to remove these security bits. From study I come to know that, By full chip erase and downloading Bootloader it can be solve.
But Bootloader of P89C51RD2 is not found. Can anybody provide me the link to download it.
One more thing , Parallel programming is the solution but Can I do the parallel programming with PLCC package?
If yes then please provide the steps to do that.
I go through http://forum.flashmagictool.com/index.php?topic=3320.0
which provides the steps to update bootloader for P89V51RD2. Is this steps are same for P89C51RD2 updating bootloader??
