The Peripheral Manager provides additional feature and is equipped with following peripherals:
•
The FRU Data Flash device contains the CP6940 FRU information
•
Internal watchdog monitoring PM operation
•
The external watchdog is implemented in glue logic. The PM will be reset if its alive signal fails. The watchdog is
disabled in case of a local update.
