在 UART 外部回送示例中,它们使用__ wfe ()宏来使其休眠,以等待中断:

int main(void)
{
    SYSCFG_DL_init();

    NVIC_ClearPendingIRQ(UART_0_INST_INT_IRQN);
    NVIC_EnableIRQ(UART_0_INST_INT_IRQN);

    /* Optional delay to ensure UART TX is idle before starting transmission */
    delay_cycles(UART_TX_DELAY);

    while (1) {
        dataReceived = false;
        txData       = txData + 1;
        DL_UART_Main_transmitData(UART_0_INST, txData);

        while (dataReceived == false) {
            __WFE();
        }
        delay_cycles(10000);
    }
}
