The AT90S1200 AVR RISC Microcontroller supports powerful and efficient addressing
modes. This section describes the different addressing modes supported in the
AT90S1200. 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).
Figure 7. Indirect Register Addressing
The register accessed is the one pointed to by the Z-register (R30).
