 * \brief  XMEGA Self-programming driver header file.
 *
 *      This file contains the function prototypes for the
 *      XMEGA Self-programming driver.
 *      If any SPM instructions are used, the linker file must define
 *      a segment named BOOT which must be located in the device boot section.
 *
 *
 *      None of these functions clean up the NVM Command Register after use.
 *      It is therefore important to write NVMCMD_NO_OPERATION (0x00) to this
 *      register when you are finished using any of the functions in this driver.
 *
 *      For all functions, it is important that no interrupt handlers
 *      perform any NVM operations. The user must implement a scheme for mutually
 *      exclusive access to the NVM. However, the 4-cycle timeout will work fine,
 *      since writing to the Configuration Change Protection register (CCP)
 *      automatically disables interrupts for 4 instruction cycles.
 *
 * \par Application note:
 *      AVR1316: XMEGA Self-programming
 *
 * \par Documentation
 *      For comprehensive code documentation, supported compilers, compiler
 *      settings and supported devices see readme.html
