Note: Flash memories are encapsulated within the Flash Memory (FM) Module. Flash control is
accomplished by the I/O to the FM over the peripheral bus, while reads and writes are completed
between the core and the Flash memories.
Note: The primary data RAM port is 32 bits wide. Other data ports are 16 bits.
