Some
instructions inhibit the "check for interrupts at the end of this
instruction" check. I'm most familiar with the 8080 EI instruction,
which enabled interrupts after the following instruction (so things
like EI;HLT didn't have a window). It seems the PDP-11 SPL behaves
the same.
I don't think it should on the PDP-11, and the documentation do not
mention any such thing.
