Addressing

MC-16LX, the address format is determined by the instruction effective

address field or the instruction code itself (implied). When the address format is given

by the instruction code itself, specify an address in accordance with the instruction

code to be used. Several varieties of addressing modes may be selected depending on

the instruction.

MC-16LX supports the following 23 types of addressing:

• Immediate (#imm)

• Register direct

• Direct branch address (addr16)

• Physical direct branch address (addr24)

• I/O direct (io)

• Abbreviated direct address (dir)

• Direct address (addr16)

• I/O direct bit address (io:bp)

• Abbreviated direct bit address (dir:bp)

• Direct bit address (addr16:bp)

• Vector address (#vct)

• Register indirect (@RWj j = 0 to 3)

• Register indirect with post increment (@RWj+ j=0 to 3)

• Register indirect with 16-bit displacement (@Rwi + disp8i = 0 to 7, @Rwj + disp16j = 0 to 3)

• Register indirect (long) with displacement (@RLi + disp8i = 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)

• Indirectly-specified branch address (@ear)

• Indirectly-specified branch address (@eam)
