The M_TEST pin provides an external connection for testing the margin of V
duced 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 fea-
tures on future card designs and will be included in this specification at that time.
Do not use.
