我认为，在文档中，省电模式只是让您知道如何处理看门狗超时NMI。如果有NMI，根据CRT0S，进程将被重定向到JNMIHAL处理程序，它已经通过XC32以弱版本实现。源是ATPIC32 LIBS/LIBPIC32／存根/默认NMI处理程序.S。所以基本上不需要做任何事情，除非您想处理WDT信息或清除RCON。如果您想拥有自己的版本的NMIIHANTHER，您可以只写一个C函数，比如“Valuy NmithHuffer-[Value]”来处理。S的信息，你也可以把原来的弱版本的nmil处理程序的ASM代码放在你的函数中。XC32 C/C++编译器的用户指南也有一些关于NMI和JNMIH-HANDLE的信息。

I think in the document, Power-Saving Modes, just gives you an idea of how to handle a Watchdog Timeout NMI.
If there is an NMI, according to crt0.S, the process will be redirected to the _nmi_handler, it's already implemented in a weak version by XC32. The source is at pic32-libs/libpic32/stubs/default-nmi-handler.S. So basically you don't need to do anything unless you want to process the WDT information or clear the RCON.
If you want to have your own version of _nmi_handler, you can just write a C function like "
void _nmi_handler(void)" to process the information, you may also put the original weak version _nmi_handler asm code within your function.
the XC32 C/C++ Compiler User's Guide also has some information about NMI and _nmi_handler.
