Notes:
* Indicates instructions not available in 8086 or 8088 systems.
**Indicates instructions that are not supported with the necessary pinout.
***The external LOCK pin is only available on some members of the Am186 and Am188 family of microcontrollers. However, LOCK internal
logic is still in effect on parts without the LOCK pin.
