怎么进入ISR的单步？

在步进过程中没有中断的方法。
在PSoC3上，用户可以通过将IE寄存器内的EA位设置为步骤0之前和步骤1之后手动进行。这是在拆卸窗口中列出的标准的8051个寄存器之一。
具有100MS中断是一个硬实时要求，单步是一个不同的领域，非实时域。不幸的是，这两个领域彼此不协调。
我希望这能有所帮助，罗伯特

  There is no build-in way to disable interrupts while stepping. 
    On PSoC3, the user can do it manually by setting the EA bit within the IE register to 0 before the step and 1 after the step.  This is one of the standard 8051 registers that is listed in the disassembly window.
    Having a 100ms interrupt is a hard real-time requirement, single step is a different domain, the non real-time domain. Unfortunately these two domains do not go well with each other.
    I hope this helps, Robert

这不是什么好消息，但我的工作一直是围绕断点移动，不使用单步功能。
在某些情况下，我尝试过的是注释全局中断使能调用，然后我可以通过一些代码。当然，在大多数情况下，这不会有多大帮助…

  This isn't any more great news, but my work around for this has been to keep moving breakpoints around and not use the single-step feature...
    One thing that I have tried in certain cases is to comment out the global interrupt enable call, then I can step through some code. Of course, in most cases this won't help much...
