The DNU/M Test pin provides an external
connection 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.
