Program and Data

Addressing Modes

The ATtiny26/L AVR Enhanced RISC microcontroller supports powerful and efficient

addressing modes for access to the Flash program memory, SRAM, Register File, and

I/O Data memory. This section describes the different addressing modes supported by

the AVR architecture. 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.

Figure 6. Direct Single Register Addressing

The operand is contained in register d (Rd).

Rd and Rr

Figure 7. Direct Register Addressing, Two Registers

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

(Rd).
