Operand address is the result of the Y- or Z-register contents added to the address con-
tained in 6 bits of the instruction word.

Data Indirect

Figure 11. Data Indirect Addressing

Operand address is the contents of the X-, Y-, or the Z-register.

Data Indirect with Pre-
decrement

Figure 12. 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.

Data Indirect with Post-
increment
