FCD-IPM includes a Dual Image Flash, capable of storing two different versions of
software in two different partitions.
Upon reset (or boot, refer to Appendix D), FCD-IPM automatically runs the
program stored in the active partition.
New software versions are loaded into the backup partition. If loading succeeds,
the backup partition becomes active and reset is automatically performed, running
the new software version. If loading fails, however, the device will still be capable
of working, since the Flash partition storing the old version is still active. Refer to
Figure 4-19.
