AT90S/LS2323/2343
The AT90S2323/2343 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 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 10. Direct Single Register Addressing
The operand is contained in register d (Rd).
Figure 11. Direct Register Addressing, Two Registers
Operands are contained in register r (Rr) and d (Rd). The result is stored in register d
(Rd).
