P-Flash phrase containing the D-Flash protection byte during the reset sequence, the DPOPEN bit will be
cleared and DPS bits will be set to leave the D-Flash memory fully protected.
Trying to alter data in any protected area in the D-Flash memory will result in a protection violation error
and the FPVIOL bit will be set in the FSTAT register. Block erase of the D-Flash memory is not possible
if any of the D-Flash sectors are protected.
