The FPROT register, described in
, can be set to protect regions in the Flash memory from
accidental program or erase. The Flash memory addresses covered by these protectable regions are shown
in the P-Flash memory map. The higher address region is mainly targeted to hold the boot loader code
since it covers the vector space. Default protection settings as well as security information that allows the
MCU to restrict access to the Flash module are stored in the Flash configuration field as described in
in the P-Flash memory map. The higher address region is mainly targeted to hold the boot loader code
since it covers the vector space. Default protection settings as well as security information that allows the
