Connected to LVDS_RF pin of the LVDS transceiver. It
allows you to select the input CLK triggering edge.
UART 1
Two signals of the I/O Expander are reserved to be used as a UART. They are connected to an RS-232
level adapter.
CAUTION!
This functionality is not supported by the current I/O Expander firmware.

CAN
The ConnectCore 6UL SBC Pro provides two CAN bus ports compatible with the CAN 2.0B protocol.
Two CAN transceivers are used on the SBC to provide transmit and receive capability between the
CAN bus and the CAN controller of the i.MX6UL. These transceivers allow signal rates up to 1 Mbps.
The CAN_STBY signal, driven by I/O expander CAN_STBY/IO34 signal, allows the standby mode for
both CAN transceivers simultaneously.
