NI 8452 able to measure SPI clock on another DIO line?

This was for troubleshooting, and now just want to see it implemented.  The SPI clock is fed back into DIO7

The goal = counting clocks in some VI.  Have a vi with read from port channel, then trying to digitize and display something.  sits at zero.  Has anyone set something like this up?   Either display the clocks or count them.  part of it is learning  the 8452

Thanks
