9.55.2.3 Addressing Modes

as understands the following addressing modes for the Z8000:

rl n
rh n
r n
rr n
rq n
Register direct: 8bit, 16bit, 32bit, and 64bit registers.
@r n
@rr n
Indirect register: @rrn in segmented mode, @rn in unsegmented mode.
addr
Direct: the 16 bit or 24 bit address (depending on whether the assembler is in segmented or unsegmented mode) of the operand is in the instruction.
address(r n )
Indexed: the 16 or 24 bit address is added to the 16 bit register to produce the final address in memory of the operand.
r n (# imm )
rr n (# imm )
Base Address: the 16 or 24 bit register is added to the 16 bit sign extended immediate displacement to produce the final address in memory of the operand.
r n (r m )
rr n (r m )
Base Index: the 16 or 24 bit register rn or rrn is added to the sign extended 16 bit index register rm to produce the final address in memory of the operand.
# xx
Immediate data xx .
