Addressing Capabilities
2.2.6 Address Register Indirect with Displacement Mode
In the address register indirect with displacement mode, the operand is in memory. The sum
of the address in the address register, which the effective address specifies, plus the sign-
extended 16-bit displacement integer in the extension word is the operand’s address in
memory. Displacements are always sign-extended to 32 bits prior to being used in effective
address calculations.
