The use of pfSPIRxIsrCallBack function in sigmastudio for sharc

Category: Software
Product Number: SigmaStudioforSharc
Software Version: CCES2.10.1 Sigmastudio v4.7

I couldn't find the SPI response message in the sigmastudio for sharc interface document, and the upper computer cannot determine whether the instruction was successfully sent. I want to use the pfSPIRxIsrCallBack function as a response, but this callback function cannot be triggered in CCES. Here is a screenshot of my code. I registered the callback function on line 85.

May I ask how to use callback functions? Will any SPI command enter a callback?
