There is another interpretation that I have just realised. If this is the right one
then whoever wrote that documentation need a dose of the clue-by-four!
But here it is :
In order to completely test the CPU logic with this diagnostic, the 'halt trap option'
must be disabled. To do this, fit jumper W9.
If the 'halt trap option' is enabled then there are some faults that the diagnostic can't
find, Therefore if W9 is not fitted a CPU module with a fault may pass the diagnostic
But that would be a very unnatural way for me to understand it, and I would think whoever
wrote something with that meaning was being deliberately confusing.
