Signal Descriptions and Pinout Tables

The following section describes the signals found on COM Express™ Type 6 connectors used for congatec GmbH modules. The pinout of the
modules complies with COM Express Type 6, rev. 3.0.
The table below describes the terminology used in this section. The PU/PD column indicates if a pull-up or pull-down resistor has been used.
If the field entry area in this column for the signal is empty, then no pull-up or pull-down resistor has been implemented by congatec.
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.
