我无法检测看门狗何时RESET。我目前正在按照用户指南中的步骤操作，指南中指出：
看门狗超时标志(WDTOF)经过检查后可确定看门狗是否导致了复位条件。 WDTOF标志必须通过软件清零。
虽然设备重置成功，但之后该标志似乎并未被设置。
我看到之前有一个关于 LPC4357 类似问题的帖子（已解决：LPC4357：无法检测到看门狗 RESET - NXP 社区），但我没有在 LPC18xx 勘误表中看到任何相关信息。
请问LPC18xx是否存在与上述相同的问题？
嗨@ejg
谢谢你的帖子！
请问您使用的是哪一款LPC18xx？
另外，你们是在什么时候审查国旗的？
如果从lpc18xx_wwdt.h调用WWDT_Init函数，它会清除中断标志，因此需要先读取WDTOF。
