Ground
It provides an external connection on R/Cs A-D for testing the margin of Vref which is
produced by a voltage divider on the module. It is not intended to be used in normal
system operation and must not be connected (DNU) in a system. This test pin may have
other features on future card designs and if it does, will be included in this specification at
that time.
