65816 Instruction Set: Opcode map

Introduction

The high nibble of the opcode is the row, the low nibble the column. Every cell is a defined instruction; there are no undocumented opcodes. In the cells:

# is an immediate operand. A cell marked ^M is 1 byte of operand when the M flag is set and 2 when it is clear; one marked ^X follows the X flag (the M and X flags). All other cells have one length.
dp direct page, abs absolute, long 24-bit, sr,S stack relative, (…) indirect, […] indirect long, rel and rell 8-bit and 16-bit relative, src,dst a block move (addressing modes).
The cell of wdm (42) is the only reserved opcode.
