9.48.2.3 Addressing Modes

as understands the following addressing modes for the Z8000:

rln

rhn

rn

rrn

rqn

Register direct: 8bit, 16bit, 32bit, and 64bit registers.

@rn

@rrn

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(rn)

Indexed: the 16 or 24 bit address is added to the 16 bit register to produce the final address in memory of the operand.

rn(#imm)

rrn(#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.

rn(rm)

rrn(rm)

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.
