| When the low 2-bits are 0x1, the NCCH is a CFA. Otherwise, it's a CXI.
| Content Type Bit-masks: RomFS = 0x1, ExeFS = 0x2, SystemUpdate = 0x4, Manual = 0x8, Child = (0x4<nowiki>|</nowiki>0x8), Trial = 0x10. When 'RomFS' is set, but not 'ExeFS', NCCH is a CFA. Otherwise when 'ExeFS' is set, NCCH is a CXI.

CXIs NCCH header signature is verified using the RSA public key stored in the accessdesc,(which follows the exheader) while CFAs NCCH header is verified with a fixed RSA public key.
