ISO7241A: SPI communication using HC-2 kit

Part Number:ISO7241A

Hi,

I am using SPIA port (J8 header) on DRV8301 HC-2 kit based on motorware software. I can see the SCLK, MISO, MOSI on the microcontroller side of the isolation IC (IS0 7241 A) however, on the other side of the IC there are no pulses observed.

I can see the isolated 3.3V on the other side of the isolation IC (IS0 7241 A) which indicates that the IC is energized. Both the enable pins on the hardware are

How can I use the SPIA
