Preliminary
Figure 1-1 System Bus Interfaces
Note:
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.
Note:
The primary data RAM port is 32 bits wide. Other data ports are 16 bits.
