NOTE

For access errors signaled on instruction prefetches, an access error

exception is generated only if instruction execution is attempted. If an

instruction fetch access error exception is generated and the FS field

indicates the fault occurred on an extension word, it may be necessary for

the exception PC to be rounded-up to the next page address to determine the

faulting instruction fetch address.
