 Mictor 38-pin MPC5xx Nexus 8-bit Cable Adapter
This adapter is used to connect the iC5000 development system to Freescale MPC56x target via Nexus debug
interface. It connects between the Debug/Trace module and the target debug connector. It can be used for targets
featuring Mictor 38-pin target debug connector with MPC5xx Nexus pinout.
The following pinout is valid on the target side:

Blue colored signals are required for trace.
Note: Mictor 38-pin MPC5xx Nexus 16-bit Cable Adapter features resettable fuses on pins 2, 9, 12, 21. The
fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current
fades away. Signals on pins 6, 8, 10, 23, 25, 27, 29, 31, 33, 35, 37 and 38 are terminated via 47 ohm resistors.
The adapter connects to the target via a 38-pin Mictor connector (Tyco Electronics: 5767055-1). A target should
feature a matching part (for example Tyco Electronics: 5767081-1 or 2-5767004-2 in the SMT technology).
