AT90S2313
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).
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).
