您好。使用GPIO中断时，中断能进入ISR，但是不能区分具体的GPIO端口。程序如下：
#define AD7606_PAR_BUSY_GPIO_BANK       5
#define AD7606_PAR_BUSY_GPIO_BANK_INT       SYS_INT_GPIO_B5INT

#define AD7606_PAR_BUSY_V1                      GPIO_TO_PIN(5, 11) //BANK5的中断口5.11
#define AD7606_PAR_BUSY_V2                      GPIO_TO_PIN(5, 9) //BANK5的中断口5.9
#define AD7606_PAR_BUSY_C                      GPIO_TO_PIN(5, 5) //BANK5的中断口5.5
#define AD7606_PAR_BUSY                               GPIO_TO_PIN(5, 4)

#define AD7606_PAR_CONVST                      GPIO_TO_PIN(5, 1)
#define AD7606_PAR_RD                               GPIO_TO_PIN(5, 2)
#define AD7606_PAR_RESET                      GPIO_TO_PIN(5, 0)

static void ad7606_irq_setup(ad7606 *ad) {
      Hwi_Params hwiParams;
      Hwi_Handle myHwi;
      Error_Block eb;

      Error_init(&eb);
      Hwi_Params_init(&hwiParams);
      hwiParams.arg = (unsigned int)ad;
      hwiParams.enableInt = FALSE;
      hwiParams.eventId = SYS_INT_GPIO_B5INT;
      hwiParams.priority = 4;
      myHwi = Hwi_create(8, ad7606_busy_hwi, &hwiParams, &eb);    //注册BANK5中断处理函数
      if (myHwi == NULL)
      LOG_FATAL("failed to create hwi");

      /* enable both interrupts */

      HWREG(SOC_SYSCFG_0_REGS + SYSCFG0_PINMUX(11)) =       (PINMUX11_BUSY_V1_ENABLE | PINMUX11_BUSY_V2_ENABLE | savePinMux);

      savePinMux = HWREG(SOC_SYSCFG_0_REGS + SYSCFG0_PINMUX(12)) & (~(SYSCFG_PINMUX12_PINMUX12_31_28 | SYSCFG_PINMUX12_PINMUX12_27_24 | SYSCFG_PINMUX12_PINMUX12_23_20 | SYSCFG_PINMUX12_PINMUX12_11_8));

你用单步调试，step into看看相应的函数值是否发生了变化
