Data Memory
Internal SRAM
The Data memory contains the I/O Memory, internal SRAM, optionally memory mapped
EEPROM and external memory if available. The data memory is organized as one continuous
memory section, as shown in
Figure 4-2.
I/O Memory, EEPROM and SRAM will always have the same start addresses for all XMEGA
devices. External Memory (if exist) will always start at the end of Internal SRAM and end at
address 0xFFFFFF.
The internal SRAM is mapped in the Data Memory space, always starting at hexadecimal
address location 0x2000. SRAM is accessed from the CPU by using the load (LD/LDS/LDD) and
store (ST/STS/STD) instructions.
