Backdoor Key Security Enable Bits — The KEYEN[1:0] bits define the enabling of the backdoor key access
to the Flash module as shown in
Nonvolatile Flag Bits — The NV[5:2] bits are available to the user as nonvolatile flags.
Flash Security Bits — The SEC[1:0] bits define the security state of the MCU as shown in
Flash module is unsecured using backdoor key access, the SEC[1:0] bits are forced to 1:0.
