Can you do Digital In or Out on the same port (byte) as PFI timing?

[Dave_Thomson]

   I'm using an M series board with three digital ports.  Port 0 is only for DIO, ports 1 and 2 can be used for DIO or PFI (e.g. clocking, triggering).  My question is:  can I do both DIO and PFI functions on any one port.  For example, on Port 1, I would like to use bits 0 to 6 as Digital Inputs and have an external clock signal go into bit 7 as a clock for Analog Out.  Can the port be mixed like this?

Thanks,

Dave,

The DIO lines on any DAQ device that uses the DAQ-STC ASIC can be configured on a per line basis, so using PFI and DIO lines on the same port will work just fine. 

You can run a quick test on this using the "Gen Dig Pulse.vi" example (found in the NI Example Finder under Browse -> Hardware Input and Output -> DAQmx -> Generate Digital Pulses).  You should be able to generate a pulse on one of the PFI lines on the board, then read that pulse back in on one of the DIO lines of that port using an external connection.
