Program and Data Addressing Modes
The AT90S2313 AVR RISC Microcontroller supports powerful and efficient addressing modes for access to the program
memory (Flash) and data memory. This section describes the different addressing modes supported by the AVR architec-
ture. In the figures, OP means the operation code part of the instruction word. To simplify, not all figures show the exact
location of the addressing bits.
Register Direct, Single Register Rd
Figure 9. Direct Single Register Addressing
The operand is contained in register d (Rd).
Register Direct, Two Registers Rd and Rr
Figure 10. Direct Register Addressing, Two Registers
Operands are contained in register r (Rr) and d (Rd). The result is stored in register d (Rd).
