1 _{This bit is reserved. User must write a 1 to this bit. Failing to do so may result in unexpected behavior.}
Nonvolatile Flash registers, shown in Table 4-4, are located in the Flash memory. These registers include
an 8-byte backdoor key, NVBACKKEY, which 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.
