Preliminary
Controller
Flash memories are encapsulated within the Flash Interface Unit (FIU). Flash control is accomplished
by the I/O to the FIU over the peripheral bus, while reads and writes are completed between the core
and the Flash memories.
The primary data RAM port is 32 bits wide. Other data ports are 16 bits.
