In the case of different NVIC priorities, the interrupt vector with the higher NVIC priority can interrupt the interrupt handler being executed.

In the case of the same NVIC priority, the interrupt vectors in the interrupt handler cannot interrupt each other. However, when the interrupt flag is set at the same time, the smaller interrupt vector in the interrupt vector table will enter the interrupt handler first.
