王工您好：
安全手册中，7.97 PLL Slip Detector。
在我们使用570过程中，是需要自己去触发PLL Slip并看ESM模块能否检测到此Slip，还是我们直接程序监控ESM模块是否存在PLL Slip错误？

Hi MingXi,

You can do both:

1. The PLL slip monitoring circuit monitors the PLLSLIP in run time. Whenever the PLL slip occurs, the flag in GLBSTAT register and ESM should be set. If ROS is set, a reset is generated.

2. You can force a PLL slip to check if an expected error is generated (flags in global status register, and ESM 1.10 and ESM 1.42)

王工：

在FMEDA计算中，针对PLL slip detector，我们如果是想将这项设置为1。

是因为570的ESM模块可以检测PLL slip 还是我们需要You can force a PLL slip to check if an expected error is generated 。

This is to test the PLL slip detection logic. You need to force a PLL slip to check if an expected error is generated
