Frozen Fault Flag Register (FCU_FFFR)
The Fault Flag Register (FCU_FFR) is copied into Frozen Fault Flag Register (FFFR) every
time the FCU goes into Fault state, in order to take a snapshot of the fault flags.
The bit description of the FCU_FFFR is the same as that of the FCU_FFR. The FCU_FFR is
read/clear whereas the FCU_FFFR is read-only. See Figure 439 and Tabl e 4 04 for details.
