#74487 - RE: 8051`s Undocumented Instructions.
Responding to: ???'s previous message
Arif,

Check the op-code map and you'll only find opcode "0xA5" available as a potential "undocumented" instruction.

This opcode has a history of being used for ICE and Debugger use, and in reference to the intel '251, as the header byte for an extended yet documented set of instructions.

regards,
p
