4. Non PICMG Connectors on the Module

This connector is a low height flex-edge connector. The overall board real estate required is significantly smaller than the 60-pin XDP debug

port connector. Compared to the 60-pin XDP debug port connector, the 26-pin XDP-SFF connector supports fewer DFX features. This is the

connector recommended for OEM/ODM designs. The 26-pin XDP-SFF debug port supports the following features on a Next Generation

Intel® Atom® Processor based Desktop and Mobile Platform:

• JTAG

• Run Control through dedicated PREQ/PRDY pins

• Reset and Powergood recovery and request signals.
