(see https://github.com/milesg-github/ppe42-tests for details) Test status is checked by periodically issuing 'info register' commands and checking the NIP value. If the NIP is 0xFFF80200 then the test successfully executed to completion. If the machine stops before the test completes or if a 90 second timeout is reached, then the test is marked as having failed. This test does not test any PowerPC instructions as it is expected that these instructions are well covered in other tests. Only instructions that are unique to the IBM PPE42 processor are tested.
