n
Memory Protection Page Attribute Register (PROG
n
_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 writeable
only by a non-debug secure entity. The NS bit is writeable only by a non-debug secure entity. For debug accesses,
the register is writeable only when NS = 1 or EMU = 1.
