Flash security Byte

Hello

 

When I study NormalDemo code, I find code as below

 

/* Program the Security Byte in the Flash Configuration Field to an unsecure value */
returnCode = pFlashProgramLongword(&flashSSDConfig, 0x40C, 4, \
(UINT32)(&unsecure_key), pFlashCommandSequence);
if (FTFx_OK != returnCode)
{
ErrorTrap(returnCode);
}

 

It seems to unlock some security function by writing 4 bytes data from 0x40C.

But I can't find any data sheet talked about memory mapping(0x40C).

Could somebody help me ??

Thanks a lot
