Interrupt Pending (IP)
Hardware sets the IP field whenever it detects an interrupt
condition, which is defined as:
If any of the status fields in the Fault Status register was
already Set at the time of setting any of these fields, it is not
treated as a new interrupt condition.
The IP field is kept Set by hardware while the interrupt
message is held pending. The interrupt message could be
held pending due to the interrupt mask (IM field) being Set
or other transient hardware conditions.
The IP field is cleared by hardware as soon as the interrupt
message pending condition is serviced.
This could be due to either:
Reserved
• When primary fault logging is active, an interrupt
• When advanced fault logging is active, an interrupt
• Hardware detected error associated with the Invalidation
