2.3 Signal Table Terminology
The following section describes the signals found on the Type 6 connectors. Table 2-2
below describes the terminology used in this section for the Signal Description tables. The
“#” symbol at the end of the signal name indicates that the active or asserted state occurs
when the signal is at a low voltage level. When “#” is not present, the signal is asserted
when at a high voltage level.
