Hello, I'm working with the MCF52233. I had secured the flash ( 4ac8 in position 0x414 ) and then i tried to write data without unsecuring temporally the flash. I sorprised when i realised the flash was written successfully. I read all the info about the Back door access in the data sheet but i don't continue understanding what is the back door access used for.
Does anybody know what is the back door access used for?
thanks in advice.
