If the first-level fetch returns either a coarse page table descriptor or a fine page table
descriptor, this provides the base address of the page table to be used. The page table is
then accessed and a second-level descriptor is returned. Figure 3-9 on page 3-15 shows
the format of second-level descriptors.
