一个“交通信号灯” ——有时被称为“信号灯”,我觉得只有我会这么说——意味着一个装有三个灯的盒子——一个是红色的, 一个是黄色的, 一个是绿色的——它告诉你是否需要停

I don't know if that translates to a spoken podcast, if that makes any sense, but look up semaphores and abortable semaphores for a good example of like how those kind of work into a more general async await workflow.
我不知道这是否适用于播客,如果这样说有意义的话, 但你可以查找信号量和可中断信号量的例子, 看看它们是如何融入更通用的异步等待工作流程中的。
A guarantee of exclusive access to a shared resource. In embedded systems, the shared resource is typically a block of memory, a global variable, or a set of registers. Mutual exclusion can be achieved with the use of a semaphore or mutex.
唯一访问共享资源的保证。在嵌入式系统中,共享的资源典型的有内存块或寄存器组。互斥现象能由使用信号灯或互斥完成。
