#137756 - favourite atomic test-and-set instructions Responding to: ???'s previous message |
Another atomic test-and-set instruction family are the eXCHange instructions, of which the '51 has a selection, too.
They are good for byte-wide "flags", though, not typical for microcontrollers. JW PS. I linked into this thread from the 'atomicity" FAQ. |
