ADS131M04: about DRDY pin signal

When I use an oscilloscope to capture the DRDY pin signal, I noticed that it jitters violently. What could be the reason for this? I'm concerned that the software might capture the wrong falling edge. How can I avoid this issue and accurately capture the signal prepared by the AD converter?

Hi, can you share the solution？

Okay, it's easy. Firstly, when I detect the falling edge of DRDY on the software, I will wait for 1~2us and then check if DRDY is at a low level. If it is, I can start collecting data
