7.4. Memory Interface

The memory interface allows the 32-bit CPU access to 16 and 8-bit devices, and allows the addition of wait states to memory
access. The memory interface allows between 0 and 31 wait states to be added. The ROM area is hardware write-protected,
a FLASH write enable bit in the ROM wait state configuration register can be used to enable write access to the ROM area.
