XDP Debug Header

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 Samtec™ 60-pin BSH-030-01 series
connector.

Notes:
1. These signals are optional, can be left as OPEN/No-Connect if debug by Intel will not be needed.
2. These CFG signals can be left as Open/No Connect if not used as a strapping signal and top side probe
will be used to debug processor.
