Other Common Notation
# Used after a signal name to identify an active-low signal (such as USBP0#)
(NxnX) When used in the description of a component, N indicates component type, xn are the relative
coordinates of its location on the D845HV and D845WN 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.
