Chapter 4 Memory Map and Register Definition
Nonvolatile FLASH registers, shown in
include an 8-byte backdoor key that optionally can be used to gain access to secure memory resources.
During reset events, the contents of NVPROT and NVOPT in the nonvolatile register area of the FLASH
memory are transferred into corresponding FPROT and FOPT working registers in the high-page registers
to control security and block protection options.
