ADS1274: Using the ready pin of the ADS1274 as an interrupt to run the spi acquisition program will get stuck at the read/write register

The controller platform is ZYNQ7010.
Use zynq's spi function interface to poll read/write data from the ADS1274. When I want to use the ready pin interrupt to read and write AD data, the program will get stuck in the read and write register in the function interface. What is this? Interrupt program is normal, you can run other parts of the program, once running spi collection program will be stuck, please help to analyze. Thank you very much!
