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 */
Hwi_enableInterrupt(ad->irq_event);
}

static void ad7606_gpio_pinmux_setup(ad7606 *ad) {
volatile unsigned int savePinMux = 0;
      //初始化5.11、5.9 、 5.5为GPIO口
savePinMux = HWREG(SOC_SYSCFG_0_REGS + SYSCFG0_PINMUX(11)) & (~(SYSCFG_PINMUX11_PINMUX11_27_24 | SYSCFG_PINMUX11_PINMUX11_19_16));

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));
