the right (low-order) and increasing to the left (high-order).
Signal Names: All signal names are printed in boldface type. Signal names that
originate in an industry-standard specification, such as PCI or IDE, are printed in the
case as found in the specification (usually uppercase). Active low signals have either
a pound sign “#” appended, or a “not” overscore bar; for example, DEVSEL# and
RESET.
