Hi,
I am working with P89C51RD2HBA(PLCC package).
When I start to download .hex files using flash magic , "Security
bit 1 is set" message is displayed.
And from ISP->ReadSecurity, I come to know that Security bits
1, 2 and 3 all are set.
Using WinISP, I can blank check, I can erase but when I press
program part it shows,"Flash programming Fail"
How to remove this security bits?
Regards
