Chapter 4 Memory Map and Register Definition
4.7.3
4.7.4
During reset, the contents of the nonvolatile location NVPROT are copied from FLASH into FPROT. This
register can be read at any time. If FPDIS = 0, protection can be increased, i.e., a smaller value of FPS can
be written. If FPDIS = 1, writes do not change protection.
56
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.
