Chapter 2 Addressing Modes
Stack pointer relative
dsp:8[SP]
The address indicated by the content of the
stack pointer (SP) plus the value indicated by
the displacement (dsp)—added including the
sign bits—is the effective address for the
operation. The stack pointer (SP) here is the
one indicated by the U flag.
However, if the addition results in a value
outside the range 00000
17 and above are ignored, and the address
returns to 00000
This addressing mode can be used with the
MOV instruction.
