CBEIE, CCIE and KEYACC bits are readable and writable while all remaining bits read 0 and are not
writable in normal mode. KEYACC is only writable if KEYEN (see
Register (FSEC)”
mass erase and erase verify operations. When writing to the FCNFG register in special mode, all
unimplemented/ reserved bits must be written to 0.
