I'm not sure whether this a simulator bug, a documentation
bug, or what. The DSP 56001 manual says that an instruction
of the form BTST #n,D is allowed, where #n is the bit number
and D is a register. The assembler allows the instruction
and generates the correct bits as per the manual. However
the simulator complains that this is an illegal instruction
and when I try to use it in my target system it bombs
(although it's difficult to tell whether this is due
to an illegal instruction or some other problem).

The description for BTST in the manual is: "Bit Test
on Memory", which makes me think that this may be a 
documentation bug which has been carried over into the
assembler.
