Based on these settings, MPTE0 spans 2
LOC value is specified, the DFLPT must generate section base-address values for each
location in the span as a linear offset to the base LOC. Even though this represents some
constraint in the view of virtual-to-physical memory mapping, it is quite common in an
embedded system to have large chunks of virtual memory to be contiguous.
The table below lists the page-table entries available in the DFLPT.
