-      Machine Mode Lockdown (mseccfg.MML) enforces strong isolation between Machine Mode and lower-privilege modes. This is a _sticky bit_
-      meaning that once set, it can only be reset on PMP Reset.
-
-      When `mseccfg.MML` is 1 (set), it redefines:
-
-      a). `pmpcfg.L` bit as:
-
-            - When `pmpcfg.L` is set, PMP rules are *enforced* on M-Mode only and *denied* on S/U-modes.
-
-            - When `pmpcfg.L` is unset, PMP rules are *enforced* on S/U-modes-only and *denied* on M-mode.
-
-      Formerly Reserved Encodings `pmpcfg.RW=01` and the encoding `pmpcfg.LRWX=1111` as *Shared-Region*.
-      A _Shared region Rule_ is *enforced* on all modes, with restrictions depending on the `pmpcfg.L` and `pmpcfg.X` bits as:
-
-            - A _Shared-Region rule_ where `pmpcfg.L` is not set can be used for sharing data between M-mode and
-              S/U-mode, so is not executable. M-mode has read/write access to that region, and S/U-mode has
-              read access if `pmpcfg.X` is not set, or read/write access if `pmpcfg.X` is set.
-
-            - A Shared-Region rule where `pmpcfg.L` is set can be used for sharing code between M-mode and
-              S/U-mode, so is not writeable. Both M-mode and S/U-mode have execute access on the region, and
-              M-mode also has read access if `pmpcfg.X` is set. The rule remains locked so that any further
-              modifications to its associated configuration or address registers are ignored until a PMP reset,
-              unless `mseccfg.RLB` is set.
-
-            - The encoding `pmpcfg.LRWX=1111` can be used for sharing data between M-mode and S/U mode,
-              where both modes only have read-only access to the region. The rule remains locked so that any
-              further modifications to its associated configuration or address registers are ignored until a PMP
-              reset, unless `mseccfg.RLB` is set.
-
-      b). Adding a rule with executable privileges that either is M-mode-only or a locked Shared-Region is not
-          possible and such `pmpcfg` writes are ignored, leaving `pmpcfg` unchanged. This restriction can be
-          temporarily lifted e.g. during the boot process, by setting mseccfg.RLB.
-
-      c). Executing code with Machine mode privileges is only possible from memory regions with a matching M-
-          mode-only rule or a locked Shared-Region rule with executable privileges. Executing code from a
-          region without a matching rule or with a matching S/U-mode-only rule is *denied*.
-
-      d). If `mseccfg.MML` is not set, the combination of `pmpcfg.RW=01` remains reserved for future standard use.
