For a memory region, there is possibility to set the mode in the form "rwxrwx", where the first "rwx" is the mode for this CPU (core) and the second "rwx" is the mode for other CPUs (cores). Examples:

  1. "------" - the region is disabled (no-touch zone).
  2. "--x--x" - the region's content can be executed.
  3. "rw-r--" - the CPU can read from and write to the region; other are not allowed to write into it.
  4. "rw-rw-" - all CPUs can read from and write to the region (shared access).
