A guide on how to use the LSE clock security system to improve clock system robustness Use guidance
■The purpose of this document is to let users understand the safety monitoring function of the N32L43x, N32L40x, and N32G43x series LSE clocks, improve the robustness of the clock system, improve the security performance of the solution, and reduce the development time and difficulty.
●Overview
■In some application scenarios, LSE failures may be encountered. Here, we propose a method by which LSE-CSS can be used to monitor LSE failures. When a failure occurs, the system clock can be switched from the LSE to the LSI to avoid the LSE failure causing the system to stop running.
