BS, ends at 0x003FFE
010 = High security; secure program Flash segment starts at end of BS,
ends at 0x003FFE
Secure space is 16K IW less BS:
101 = Standard security; secure program Flash segment starts at end of
BS, ends at 0x007FFE
001 = High security; secure program Flash segment starts at end of BS,
ends at 0x007FFE
Secure space is 32K IW less BS:
100 = Standard security; secure program Flash segment starts at end of
BS, ends at 0x00FFFE
000 = High security; secure program Flash segment starts at end of BS,
ends at 0x00FFFE

00 = Secure RAM is 4096 bytes less BS RAM
GSS<1:0> FGS Immediate General Segment Code-Protect bits
11 = User program memory is not code-protected
10 = Standard security; general program Flash segment starts at end of
SS, ends at EOM
0x = High security; general program Flash segment starts at end of SS,
ends at EOM
