MC-16LX, the address format is determined by the instruction effective
address field or the instruction code itself (implied). When the address format is
determined by the instruction code itself, specify an address in accordance with the
instruction code used. Some instructions permit the user to select several types of
addressing.

• Abbreviated direct bit address (dir:bp)
• Direct bit address (addr16:bp)
• Vector address (#vct)
• Register indirect (@RWj j = 0 to 3)
• Register indirect with pos
t increment (@RWj+ j = 0 to 3)
• Register indirect with displacement (@RWi + disp8 i = 0 to 7, @RWj + disp16 j = 0 to 3)
• Long register indirect with displacement (@RLi + disp8 i = 0 to 3)
• Program counter indirect with displacement (@PC + disp16)
• Register indirect with base index (@RW0 + RW7, @RW1 + RW7)
• Program counter relative branch address (rel)
• Register list (rlst)
• Accumulator indirect (@A)
• Accumulator indirect branch address (@A)
