Triggering

The configuration files provide some logic analyzer based trigger set-ups that utilize the pre defined symbols described earlier.

Remember to always use DS for default storage, and use default store to fill memory.

The probe-generated Event Code field makes it easy to trigger on particular packet types, using the pre-defined symbols. When triggering on Event Code always qualify it with:

• DS =1 (for valid data)

• PSS[1] =1 (The start of packet flag).

• CS (Already included in pre-defined Event Code symbol definitions)

The probe-generated Packet Recognizer flags (Pat_Rec_3,2,1) make it easy to trigger on packets based on header or data bit patterns in the first 24 bytes of each packet.

These flags are always valid, pulse once at the start of each recognized packet, and do not need any other bits to qualify them.
