About the USER I/O connector pinouts
The USER Input/Output (IO) port is used to set up custom input or output connections to your target.
The USER I/O connector is a 10-way 2.54mm pitch Insulation Displacement Connector (IDC) header
that mates with IDC sockets mounted on a ribbon cable. The USER IO port is at the rear of the
DSTREAM-ST unit.
The following figure shows the pin connector details.
You must establish a common ground between the DSTREAM-ST unit and the target hardware before
you connect any of the USER I/O signals.

This is a user input bit. It has a 100K weak pull-up to the unit
internal +3.3V supply, and requires a V
V
of 0.8V. It can safely be driven by 5V logic levels, and has
il(max)
Electro Static Discharge (ESD) protection greater than the 2kV
human body model.
This pin is not currently supported by the DSTREAM-ST firmware.
