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.
Register Direct, Single
Register Rd Figure 6. Direct Single Register Addressing
The operand is contained in register d (Rd).
Register Direct, Two Registers
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).
