The ATtiny28 AVR RISC microcontroller supports powerful and efficient addressing
modes. This section describes the different addressing modes supported in the
ATtiny28. 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 8. Direct Single Register Addressing
The operand is contained in register d (Rd).
The register accessed is the one pointed to by the Z-register (R31, R30).
