3. Memory Management Unit (MMU)
3.3.2
The SH-4 supports a 29-bit external memory space. The external memory space is divided into
eight areas as shown in figure 3.5. Areas 0 to 6 relate to memory, such as SRAM, synchronous
DRAM, DRAM, and PCMCIA. Area 7 is a reserved area. For details, see section 13, Bus State
Controller (BSC).
