[BFM #22] Save/Restore Configuration

This BFM supports two bits that allow the default configuration of the BFMs to be restored and the
configuration from BFMs to be stored into Flash ROM. Both bits will be reset automatically if the restore or
save procedure is completed.
Note
• If both flags are set simultaneously, the corresponding BFMs and Flash ROM will be reset to factory default
settings.
• If only bit 1 is set, corresponding BFM areas are restored to factory default values but not stored in Flash
ROM.
After changing the configuration, BFM #22 bit 0 has to be set ON to store these changed configuration
BFMs to Flash ROM.
Object dictionary settings can be stored in Flash ROM and Object dictionary default settings can be restored
using CIF commands.
