- The 6811 Processor: references
- The official Motorola 68HC11A8 Data Sheet. Fairly cryptic...
- A Motorola 6811 Manual. It is a nicely written refresher on many concepts of assembly language applied to the 6811.
- Check Section 3.2 on addressing modes (inherent, direct, extended, indexed, relative).
- Get a refresher for the different instruction types (arithmetic, shifts, control, etc) in Section 3.4.
- The condition code register is covered in Section 3.5. Skip Section 4.
- M68HC11 Technical Reference, from Motorola.
- Section 6.5 shows the instructions in logical groups.
- M68HC11 Pocket Reference.
- Very useful, on Page 15, a list of all the opcodes supported by the 6811, in numerical (hex) order.
- 68HC11A8 Technical Reference: a hardware & engineering description. of the 6811, its ports, and how it operates.
- See Section 10 for a cycle-by-cycle description of the execution of each instruction.
- See Appendix A, Figure A-14 for the timing diagram of a typical (multiplexed expansion) memory access.
- 6811 Instruction Set, with hexadecimal opcodes. A reverse map, from hex to instructions can be found here.
- 2-Page List of all the 6811 Instructions
- Software for the 6811
