MPC5xxx and SPC56 50-pin 16-bit Nexus target pinout
Blue colored signals are required for trace.
Note: 50-pin Samtec MPC5xxx Nexus 16-bit Cable Adapter features resettable fuses on pins 2, 4, 6, 8, 10, 12, 16
and 20. These protect debug signals against overcurrent and cycle back to a conductive state after the excessive
current fades away. All other signals are protected via 47 ohm serial resistor.
The adapter connects to the target via a 50-pin Samtec connector (SAMTEC ERM8-025-01-L-D-EM2). A target
should feature a matching part (for example SAMTEC - ERF8-025-05.0-L-DV in the SMT technology).
