Memory Mapping
Internal SRAM
Internal ROM
Internal Flash
After reset and until the Remap Command is performed, the SRAM is only accessible at address
0x0020 0000. After Remap, the SRAM also becomes available at address 0x0.
The SAM7S Series embeds an Internal ROM. The ROM contains the FFPI and the SAM-BA
program.
The internal ROM is not mapped by default.
At any time, the Flash is mapped to address 0x0010 0000. It is also accessible at address 0x0
after the reset and before the Remap Command.
