楼主你好，kinetis的watchdog使用注意项在我们的用户手册中已经写了：
The write to the SRVCOP register that services (clears) the COP counter should not be
placed in an interrupt service routine (ISR) because the ISR could continue to be
executed periodically even if the main application program fails.
If the bus clock source is selected, the COP counter does not increment while the
microcontroller is in debug mode or while the system is in stop (including VLPS or LLS)
mode. The COP counter resumes when the microcontroller exits debug mode or stop
mode.

窗口模式，为什么一定要在75%喂，这样设计有什么好处 ？
在前面有XD提到过窗口看门狗，用来看窗口进程，倒也可以理解，只是FSL这个要求75%喂狗，参不透有什么弦机
(⊙o⊙)…~~~~ 这回复 。。。 膜拜~~ 您是说相声的吧~
