This section describes the different memories in XMEGA. The AVR architecture has two main
memory spaces, the Program Memory and the Data Memory. Executable code can only reside
in the Program Memory, while data can be stored both in the Program Memory and the Data
Memory. The Data Memory includes both SRAM, and an EEPROM Memory for non-volatile data
storage. All memory spaces are linear and require no paging. Non-Volatile Memory (NVM)
Flash Program Memory
