Addressing Modes

Register Direct, Single

Register Rd

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 architecture. In the fig-

ures, OP means the operation code part of the instruction word. To simplify, not all

figures show the exact location of the addressing bits.

Figure 9. Direct Single Register Addressing

The operand is contained in register d (Rd).

Rd and Rr

I/O Direct

Operands are contained in register r (Rr) and d (Rd). The result is stored in register d

(Rd).
