Figure 15. Data Indirect Addressing
Operand address is the contents of the X-, Y-, or the Z-register.
Figure 16. Data Indirect Addressing with Pre-decrement
The X-, Y-, or the Z-register is decremented before the operation. Operand address is
the decremented contents of the X-, Y-, or the Z-register.
Figure 17. Data Indirect Addressing with Post-increment
The X-, Y-, or the Z-register is incremented after the operation. Operand address is the
content of the X-, Y-, or the Z-register prior to incrementing.
