6502 opcodes list
How many opcodes are there in 6502?
Starting from Graham's table, Michael Steil constructed a 3 column table containing the opcode, the mnemomic, the addressing mode and the number of clock cycles.10 fév. 2022
How many instructions are there in 6502?
Of the 256 possible opcodes available using an 8-bit pattern, the original 6502 uses 151 of them, organized into 56 instructions with (possibly) multiple addressing modes.
Depending on the instruction and addressing mode, the opcode may require zero, one or two additional bytes for operands.The 6502 has one main 8-bit accumulator register and two auxiliary 8-bit index registers called X and Y.
The index registers are often used as array subscripts when referencing memory.
Instructions are one, two, or three bytes in length.
