3.2.2 Multiplexed signals
As stated more times in the previous paragraphs, most of the signals available on the Qseven® Card Edge Connector can be reprogrammed to implement
different functionalities, according to the i.MX6 pin-multiplexing possibilities.
For this reason, in the following table is shown a complete list of all the multiplexing possibilities offered by this module.
The signals are grouped in logical ports, where each logical port represents one of the standard functionalities (if applicable) of the Qseven modules. Please be
aware that sometimes the multiplexing can lead to conflicts (i.e., the same functionality is available on 2 or more logical ports). This situation is evidenced in the last
column of the following table.
When the i.MX6 Signal is marked in bold italic (like
WAKE#
), it means that the standard function is managed through SECO BSP, it is not native of the i.MX6
processor.
