Fault Collection and Control Unit (FCCU)
• Read or clear the FCCU freeze registers
• Lock the FCCU configuration registers
• Read the ALARM timer
• Read the SMRT timer
• Read the Watchdog timer
• Load the NVM configuration (only for test purposes)
Some critical operations (OP1, OP2, OP16, and OP31) require a key as defined in the FCCU_CTRLK
register.

Description
NVM configuration loaded
0 No NVM configuration loaded.
1 NVM configuration loaded.
At the end of the reset PHASE3, NVML = 1 and OPS = 11 if the NVM interface of the FCCU is
correctly driven by the SSCM interface.
This bit can be read and cleared (via OP15 operation) by the software.
