For debug purposes, it is possible to read and write the user data and
the ECC value directly from/to the SRAM memory. For these debug accesses a register
interface is available.
By the debug access and writing incorrect data + ECC values into the system memory,
the single and double bit ECC errors may be simulated for checking the software error handling.
The debug registers may be modified only in a special mode.
The tested address 0x3000 is excluded from linker use - see prm linker file.
I hope it helps you.
