* Current TriCore devices feature only one AGBT lane while the Active Probe hardware is ready
for future devices which could have more AGBT lanes.
Blue colored signals are trace signals.
Signal direction definition:
O - Output from the Active Probe to the target microcontroller
I - Input to the Active Probe from the target microcontroller
B
– Trigger connector – Provision for future functional extensions. No functionality at the
