Looking for help using the SPI on a USB-8451 to interface to a SC16IS752

[sdrochek3]

Trying to interface the USB-8451 to a circuit that is using a SC16IS752 Daul UART set up in the SPI mode. This involves setting up the UARTS and then communicating with the serial ports. Using LabVIEW and can send but not recieving anything, I'm assuming it's because I haven't sent it any valid commands.

Any help would be great!
