TABLE 9 - HEXADECIMAL VALUES OF MACHINE CODES

Opcodes

The Opcode and Mnemonics opcode reference tables are both complete listings that contain both the Opcode instruction and the HEX equivalant in all available addressing modes. The first table is arranged sequentially by the binary opcodes, while the second table is arranged alphabetically by the Mnemonic instructions.

At the end of the second table there are data tables containing information on Bit transfer/manipulation, branch instructions, inter-register instructions, and general register and stack information. These are all helpful to the serious assembly language programmer, who should always have one.

Where the 6309 differs from the 6809, the 6309 specific details are highlighted in turquoise.

6309 Instructions generally take one less instruction cycle to execute than the 6809.
This makes the 6309 run twice as fast as the 6809 for many instructions!
