that's odd. i must have not added sc/scv unit tests
to ISACaller. these should be added (into trap_cases.py)
as it is important to verify the pseudocode when in
equivalent of qemu-system mode (the default only option
up until this bugreport)

with an undefined variable "vectored" (sigh)

the unit test will be like this:


except there must be a stop/check when PC=0xC00.
