我想求证一个问题，是不是BF533的SPORT RX和TX中断不能同时开启（当然不是指同时发生）我将初始化函数写成这样写

void Init_Interrupts(void)
{
// Set Sport0 RX (DMA1) interrupt priority to 2 = IVG9
*pSIC_IAR0 = 0xffffffff;
*pSIC_IAR1 = 0xfffff22f;
*pSIC_IAR2 = 0xffffffff;

// assign ISRs to interrupt vectors
// Sport0 RX ISR -> IVG 9
register_handler(ik_ivg9, Sport0_RX_ISR);

register_handler(ik_ivg9, Sport0_TX_ISR);

// enable Sport0 RX interrupt
*pSIC_IMASK = 0x00000600;
}

结果只有 Sport0_RX_ISR好使，而将初始化函数写成

void Init_Interrupts(void)
{
// Set Sport0 RX (DMA1) interrupt priority to 2 = IVG9
*pSIC_IAR0 = 0xffffffff;
*pSIC_IAR1 = 0xfffff22f;
*pSIC_IAR2 = 0xffffffff;

// assign ISRs to interrupt vectors
// Sport0 RX ISR -> IVG 9
register_handler(ik_ivg9, Sport0_RX_ISR);

register_handler(ik_ivg10, Sport0_TX_ISR);

// enable Sport0 RX interrupt
*pSIC_IMASK = 0x0000060
}结果还是只有 Sport0_RX_ISR好使，我尝试将DMA1（对应 Sport0_RX）在完成相应功能后不使能（即*pDMA1-COFIG=0x0000;）发现还是解决不了这个问题

那我的初始化设置是不是还应该是这样的呢？

void Init_Interrupts(void)
{
// Set Sport0 RX (DMA1) interrupt and Sport0 TX (DMA2) interrupt  priority  to 2 = IVG9
*pSIC_IAR0 = 0xffffffff;
*pSIC_IAR1 = 0xfffff22f;
*pSIC_IAR2 = 0xffffffff;

// assign ISRs to interrupt vectors
// Sport0  ISR -> IVG 9
register_handler(ik_ivg9, Sport0_ISR);

// enable Sport0 RX interrupt and Sport0 TX interrupt
*pSIC_IMASK = 0x00000600;
}
