APPENDIX C - MACHINE CODE TO INSTRUCTION CROSS REFERENCE

PDF pages 199-202

C.1 INTRODUCTION

This appendix contains a cross reference between the machine code, represented in hexdecimal and the instruction and addressing mode that it represents. The number of MPU cycles and the number of program bytes is also given. Refer to Table C-1.

Table C-1. Machine Code to Instruction Cross Reference
LEGEND:
  ~Number of MPU cycles
(less possible push pull or indexed-mode cycles)
#Number of program bytes
-Denotes unused opcode

NOTE: All unused opcodes are both undefined and illegal
