Key: aaa = Random access address
All 1s = All PA:AA outputs HIGH
AS = All selected devices
HPD = Highest-Priority device
HPMA = Highest-Priority Match address
n/a = Not applicable
n/c = No change
NFA = Next Free address
NFD = Highest-Priority device with a Free location
s = Segment (L for DSC LOW, H for DSC HIGH)
S = Selected device
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.
