MC56F84789 FDPROT unprotect DFlash area

I am trying to program the Dflash area of the MC56F84789 which is also called Secondary (boot) program data flash.

But the FDPROT reg. = 0x00 what means that "Data Flash region is protected". I have tried to simply write to the register but the value read back is always 0x00.

What am I doing wrong?

In case of writing and reading in to the FSTAT and FPROT everything is OK.

And to mention it is done in debug mode.
