Definition
CLK
Logic analyzer reference clock (differential). This provides a LA
compatible timing reference clock for capture of all signals to the
LA, with fine capture phase adjust using the native LA clock edge
offset capabilities.
QUAL
Out
Store qualifier:
1 = store
0 = do not store
FRAME
Out
I/O
Drives 1 when LAI pins are valid level. Should be connected to
pull down on LAI board to detect when LAI pins are tri-stated
and LA should ignore data.
EV[3:0]
Inter-AMB event bus for cross-triggering (wired-OR, high active,
slow).This four bit event bus allows multiple AMB (and similar)
LAIs to be programmed to inter-communicate locally detected
matching and/or filtering opportunities events (cross-triggering
and cross-qualification).
