10 / 82 page 10 8067D–AVR–08/08 XMEGA A1 The Program Flash memory space is divided into Application and Boot sections. Both sections have dedicated Lock Bits for setting restrictions on write or read/write operations. The Store Pro- gram Memory (SPM) instruction must reside in the Boot Section when used to write to the Flash memory. A third section inside the Application section is referred to as the Application Table section which has separate Lock bits for storage of write or read/write protection. The Application Table sec- tion can be used for storing non-volatile data or application software. The Application Table Section and Boot Section can also be used for general application software. 7.4 Data Memory The Data Memory consist of the I/O Memory, EEPROM and SRAM memories, all within one lin- ear address space, see Figure 7-2 on page 10. To simplify development, the memory map for all devices in the family is identical and with empty, reserved memory space for smaller devices. Figure 7-1.
