On CQ7-A30 carrier board is also available a single row, 7-pin p2.54mm pin header, for the connection of legacy PS/2
peripherals (mouse and/or keyboard), managed by the LPC Super I/O W83627DHG (the same that manages
the serial ports available on combo connector CN12).

The LPC bus, used to manage the devices previously described in par. 3.3.15 and 3.3.17 is
also carried out on a dual row, 14 pin, P2.54mm standard pin header, with
the pinout shown in the table on the left.

Please remember that Qseven
specifications rel.2.0 share, on the same pins of the card
edge connector, the LPC signals with eight general Purpose I/Os; this means that whatever
