11.5.1
Data memory protection is assigned on a regional basis. Default manipulation of the DMPU is done on a
global region. The DMPU has control registers that contain the following information: region protection
on/off, region base address, region size, and the region’s access permissions. Each region’s protection
attributes can be turned on or off by configuring the global region attribute register’s enable attribute bit
(L2U_GRA[ENRx]).
During each load or store access from the RCPU to the U-bus, the address is compared to the value in the
region base address register of each enabled region. Any access that matches the specific region within its
appropriate size, as defined by the region attribute register’s region size field (L2U_RAx[RS]), sets a
match indication.
When more than one match indication occurs, the effective region is the region with the highest priority.
Priority is determined by region number; highest priority corresponds to the lowest region number, e.g.
region 0 is highest priority, while region 3 is lowest.
When no match occurs, the effective region is the global region, which has the lowest priority.
The region attribute register also contains the region’s protection fields. The protection field (PP) of the
effective region is compared to the access attributes. If the attributes match, the access is permitted. When
the access is permitted, a U-bus access may be generated according to the specific attribute of the effective
region.
