68	  If enabled, flash is erased as necessary when receiving new firmware,
69	  instead of erasing the whole image slot at once. This is necessary
70	  on some hardware that has long erase times, to prevent long wait
71	  times at the beginning of the DFU process.

79	  integrity.  It can be used to verify flash integrity after received
80	  a new firmware.  This is useful to avoid firmware reboot and test.
81	  Another use is to ensure that firmware upgrade routines from internet
82	  server to flash slot are performing properly.
