In-System Programmable Flash Program Memory
The XMEGA D4 devices contain On-chip In-System Programmable Flash memory for program
storage, see
Flash address location is 16 bits.
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 Program 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.
Figure 7-1.
The Application Table Section and Boot Section can also be used for general application
software.
