Hi infineon

我们当前使用了贵司的电源管理芯片TLF35584在项目中,在查阅安全手册的时候,发现有一条与看门狗相关的测试程序(如下图所示),这里提到在这项测试中,MCU的复位会被激活(且第二级安全关断路径也倍激活)。

我的疑问点是:

         1、这项测试会真实造成MCU重新复位程序吗?

         2、如果上一条是正确的,那是不是意味着程序需要跑两遍?这大大延长了上电时间,是否有推荐方法去控制。

Hi Leon,

1. ROT被拉低,MCU就会被RESET。

2. 方法可以参考一下datasheet中的 11.7 Microcontroller Programming Support

将MPS拉高至5V, 在programming和debug的过程中就不用担心MCU复位问题了。

希望可以解决你的疑问
