Primary Pending Fault (PPF)
This bit indicates if there are one or more pending faults logged in 

the fault recording registers. Hardware computes this bit as the 

logical OR of Fault (F) fields across all the fault recording registers 

of this remapping hardware unit.
0 = No pending faults in any of the fault recording registers

1 = One or more fault recording registers has pending faults. The 

FRI field is updated by hardware when the PPF bit is set by 

hardware. Also, depending on the programming of Fault Event 

Control register, a fault event is generated when hardware 

sets this field.

Primary Fault Overflow (PFO)
Hardware sets this bit to indicate overflow of fault recording 

registers. Software writing 1 clears this bit. When this bit is set, 

hardware does not record any new faults until software clears this 

bit.
