Chapter 4 Memory
4.6.3
Bits 7 through 5 may be read or written at any time. Bits 4 through 0 always read 0 and cannot be written.
4.6.4
During reset, the contents of the nonvolatile location NVPROT is copied from flash into FPROT. Bits 0,
1, and 2 are not used and each always reads as 0. This register may be read at any time, but user program
writes have no meaning or effect. Background debug commands can write to FPROT.
60
Background commands can be used to change the contents of these bits in FPROT.

Enable Writing of Access Key — This bit enables writing of the backdoor comparison key. For more detailed
information about the backdoor key mechanism, refer to
0 Writes to 0xFFB0–0xFFB7 are interpreted as the start of a flash programming or erase command.
1 Writes to NVBACKKEY (0xFFB0–0xFFB7) are interpreted as comparison key writes.
Open Unprotected Flash for Program/Erase
0 Entire flash memory is block protected (no program or erase allowed).
1 Any flash location, not otherwise block protected or secured, may be erased or programmed.
