Clock cycles are given for 8-bit/16-bit operations.2. Clock cycles are given for jump not taken/jump taken.3. Clock cycles are given for interrupt taken/interrupt not taken.4. If TEST = 0Shading indicates additions and enhancements to the 8086/8088 instruction set. See Appendix A, “80C186Instruction Set Additions and Extensions,” for details.D-7
