FTFL_FPROT1 is 4002_0000h base + 12h offset = 4002_0012h
FTFL_FPROT0 is 4002_0000h base + 13h offset = 4002_0013h
Program Flash Region Protect
Each program flash region can be protected from program and erase operations by setting the associated
PROT bit.
In NVM Normal mode: The protection can only be increased, meaning that currently unprotected
memory can be protected, but currently protected memory cannot be unprotected. Since unprotected
regions are marked with a 1 and protected regions use a 0, only writes changing 1s to 0s are accepted.
This 1-to-0 transition check is performed on a bit-by-bit basis. Those FPROT bits with 1-to-0 transitions
are accepted while all bits with 0-to-1 transitions are ignored .
In NVM Special mode: All bits of FPROT are writable without restriction. Unprotected areas can be
protected and protected areas can be unprotected.
Restriction: The user must never write to any FPROT register while a command is running (CCIF=0).
Trying to alter data in any protected area in the program flash memory results in a protection violation
error and sets the FSTAT[FPVIOL] bit. A full block erase of a program flash block is not possible if it
contains any protected region.
Each bit in the 32-bit protection register represents 1/32 of the total program flash .
