Description
The number of entries in the IMMU equals (IMMU SZ) + 1. Not used
in single-MMU or MPU systems.
Specifies the number of entries in the DMMU or in the shared MMU in
single-MMU systems. The number of entries in the DMMU or shared
MMU equals (DMMU SZ + 1). In systems with MPU, DMMU SZ
equals the number of MPUAR entries.
