AT90S/LS8535
The AT90S8535 AVR RISC microcontroller supports powerful and efficient addressing
modes for access to the program memory (Flash) and data memory (SRAM, register file
and I/O 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 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).
Figure 11. I/O Direct Addressing
Operand address is contained in six bits of the instruction word. n is the destination or
source register address.
