Memory Address Map
The SH7780 supports 32-bit virtual address space, and supports both 29-bit and 32-bit physical
address spaces (normal mode and extended mode). For details of mappings from the virtual
address space to the physical address spaces, see section 7, Memory Management Unit (MMU).
The external memory space of the SH7780 consists of the LBSC space, DDRIF space and PCIC
space. The LBSC has up to 384 Mbytes, the DDRIF has up to 256 Mbytes and the PCIC has up to
512 Mbytes external memory space individually and the SH7780 can control the external memory
space up to 1152 Mbytes totally. Areas 0, 1, and 6 are controlled by the LBSC. Areas 2, 4, and 5
are controlled by the LBSC, DDRIF or PCIC that depends on the setting of the memory address
map select register (MMSELR) of the LBSC. Note that area 3 is for the DDRIF. For details, see
section 11, Local Bus Sate Controller (LBSC), section 12, DDR-SDRAM Interface (DDRIF) or
section 13, PCI Controller (PCIC).
Figure 1.3 shows the physical address space of the SH7780. Figure 1.4 shows the relationship
between the AREASEL bits and the memory address map. The 32-bit physical address space
corresponds with the address space of the SuperHyway bus.
