您好,有个问题想请教一下。对于S32K312芯片的看门狗模块,超时过后可以配置成两种回应方式。第一种是对于任何超时,产生复位。第二种方式,是第一次超时产生中断,第二次超时产生复位。我理解的是,第一次超时的时间是我们设置的喂狗时间,但我不知道第二次超时的时间是指什么时间。想请您帮忙解答一下。期待您的回复!

Hello @夏超,

This is the same timeout.

This is all explained in the S32K3xx Reference Manual, Chapter 66 Software Watchdog Timer (SWT).

NXP provides two RTD drivers SWT_Ip and MCAL WDG that you can use to configure the HW.

 

Please let me know if you have any specific questions,

 

Regards.

Daniel
