XMEGA A3U

7.4 Data Memory

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, see Figure 7-2 on page 11. To simplify development, I/O Memory, EEPROM

and SRAM will always have the same start addresses for all XMEGA devices.
