6.4 XDP Debug Header
Connector Type: Molex 26-pin 52435-2671
The debug port is a connection into a target-system environment that provides access to JTAG,
run control, system control, and observation resources. The XDP target system connector is a
Molex 26-pin 52435-2671 connector. Specific plating types, locking clips, and alignment pin
details of this connector can be obtained from Molex. No specific plating types, locking clips or
alignment pins are required for the XDP tool.
