Figure 13. Data Indirect with Displacement
Operand address is the result of the Y- or Z-register contents added to the address con-
tained in six bits of the instruction word.
Figure 14. Data Indirect Addressing
Operand address is the contents of the X-, Y-, or Z-register.
Figure 15. Data Indirect Addressing with Pre-decrement
The X-, Y-, or Z-register is decremented before the operation. Operand address is the
decremented contents of the X-, Y-, or Z-register.
