Other Common Notation
# Used after a signal name to identify an active-low signal (such as USB#)
(NxnX) When used in the description of a component, N indicates the component type, xn are the
relative coordinates of its location on the D850MD and D850MV boards, and X is the instance
of the particular part at that general location. For example, J5J1 is a connector, located at 5J.
It is the first connector in the 5J area.
