Fault status register (FSR)
Table 3-9 shows the various access permissions and controls supported by the data
MMU, and how these are interpreted to generate faults.
Alignment faults can write either b0001 or b0011 into FSR[3:0].
Invalid values can occur in the status bit encoding for domain faults. This happens when
the fault is raised before a valid domain field has been read from a page table
description.
Aborts masked by a higher priority abort can be regenerated by fixing the cause of the
higher priority abort, and repeating the access.
Alignment faults are not possible for instruction fetches.
The instruction FSR can also be updated for instruction prefetch operations
