¡ Semiconductor
MSM7630
2.1 ROM Space
ROM space is assigned to 0x00000000-0x0FFFFFFF. When this space is accessed the ROM signal goes
"L".
2.2 SRAM Space
SRAM space is assigned to 0x10000000-0x1FFFFFFF. When this space is accessed the SRAM signal
goes "L".
2.3 DRAM Space
DRAM space is assigned to 0x20000000-0x2FFFFFFF. When this space is accessed the DRAM
controller outputs a signal required for DRAM access.
2.4 General Device Space
General device space is assigned to 0x40000000-0x7FFFFFFF. When this space is accessed the AS
signal goes "L". This space is used to access general devices external to the MSM7630.
2.5 Internal ROM Space
Internal ROM space is assigned to 0xC0000000-0xCFFFFFFF. It is used to access internal ROM.
This space is not used by the MSM7630. Accesses to this space will cause instruction access
exceptions or data access exceptions.
2.6 Internal RAM Space
Internal RAM space is assigned to 0xD0000000-0xDFFFFFFF. It is used to access internal RAM.
This space is not used by the MSM7630. Access to this will cause instruction access exceptions or data
access exceptions.
2.7 Register Space
Register space is assigned to 0xE0000000-0xFFFFFFFF. Within this space, 0xF8000000-0xFFFFFFFF
is assigned for standard I/O and system registers.
