Hello wbj5238@163.com,
Unfortunately, I can't see the image attached, but I assume that your question is related to how to change the default clock configuration that comes with our MPC Toolbox. So for a detailed explanation please have a look on this thread Clock Configuration of MPC5744P using MBD
But before performing any change please be sure that you read the Reference Manual and consider all the clock values constrains in hw.
Hope this helps,
Marius
