WebAug 27, 2024 · Solution 1. A trap is an exception in a user process. It's caused by division by zero or invalid memory access. It's also the usual way to invoke a kernel routine (a system call) because those run with a higher priority than user code. Handling is synchronous (so the user code is suspended and continues afterwards). WebInterrupts will typically be used to execute a few lines of code by the ARM core (NVIC, interrupt handlers, etc.). Events don't necessary execute code but can signal …
