Each section descriptor in the first-level translation table specifies the complete translation properties for a 1-MiB section or a 16-MiB supersection.
Supersection descriptors must be repeated 16 times, because each descriptor in the first-level translation table describes 1 MiB of memory. If an access points to a descriptor that is not initialized, the MMU will behave in an unpredictable way.
