Hello everyone, When an interrupt occurs (e.g. packet reception), its ISR is going to be executed. What will happen if another interrupt (e.g. another packet reception or timer fires) occurs before the ISR for the previous interrupt finishes? If the ISR is preempted, then interrupts can be nested and the last interrupt will always be served first? If it depends on the priorities of these interrupts, where can I find their priorities? Any explanation will be highly appreciated.
