MSP430在进入睡眠后，如果发生事件产生中断，那么单

片机会退出睡眠，自动执行中断程序，但是当中断返回时，主

程序又重新进入睡眠状态。如果要在发生中断后，主程序需

要退出睡眠，那么需要在中断程序中修改SP堆栈中的内容，

C语言没有指令可以修改堆栈内的内容，可以采用C语言与

汇编语言混合编程的方法解决此问题。-MSP430 into sleep, and if events have disrupted, SCM will withdraw from sleep, interrupted proceedings automatically, but when interrupted return, the main program to re-enter the state of sleep. If in the event of disruption, from the main program needs sleep, then the need to interrupt proceedings to amend the SP stack, C language instruction can not change the contents of stack can be used C and Assembly Language Programming hybrid method to solve this problem.
