All 1s = All PA:AA outputs HIGH
NFA = Next Free address
AS = All selected devices
NFD = Highest-Priority device with a Free location
HPD = Highest-Priority device

n/a = Not applicable
The "Scope" of a control state describes which devices respond in a multi-CAM system.
The "PA:AA" field describes what is output on the PA3–0:AA11–0 bus as a result of the control state.
/AV is HIGH unless otherwise noted.
DSC must be LOW if "s" is not indicated.
