Atmel AVR - 2.6. Data Indirect; 2.7. Data Indirect with Pre-decrement

2.6. Data Indirect
Figure 2-6. Data Indirect Addressing
Operand address is the contents of the X-, Y-, or the Z-register. In AVR devices without SRAM, Data
Indirect Addressing is called Register Indirect Addressing. Register Indirect Addressing is a subset of
Data Indirect Addressing since the data space form 0 to 31 is the Register File.
2.7. Data Indirect with Pre-decrement
Figure 2-7. 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.
