7.10.2.3 Programmable Range n Memory Protection Page Attribute Register (PROGn_MPPA)
The programmable address memory protection page attribute register holds the permissions for the region. This
register is writeable only by a non-debug supervisor entity. If NS = 0 (secure mode) then the register is also only
writeable by a non-debug secure entity. The NS bit is only writeable by a non-debug secure entity. For debug accesses
the register is writeable only when NS = 1 or EMU = 1.
