2.3.2.3
All bits read 0 and are not writable in normal mode.
2.3.2.4
The FCNFG register enables the Flash interrupts and gates the security backdoor writes.
CBEIE, CCIE and KEYACC bits are readable and writable while all remaining bits read 0 and are not
writable. KEYACC is only writable if KEYEN (see
