如何在程序运行的过程中开启/关闭管脚中断？

我想程序运行的过程中开启/关闭管脚中断，通过以下方式没有成功，请问正确的方式是什么？

void CyCx3ImuIntEnable(void)
{
    CyU3PGpioSimpleConfig_t gpioConf;
    CyU3PReturnStatus_t status = CY_U3P_SUCCESS;
    /* Configure CLOVER_IMU_INT pin*/
    gpioConf.outValue = CyFalse;
    gpioConf.driveLowEn = CyFalse;
    gpioConf.driveHighEn = CyFalse;
    gpioConf.inputEn = CyTrue;
    gpioConf.intrMode = CY_U3P_GPIO_INTR_POS_EDGE;
    status = CyU3PGpioSetSimpleConfig(CLOVER_IMU_INT,  gpioConf);
    if (status != CY_U3P_SUCCESS)
    {
        Cx3Err("[GPIO] imu interrupt pin enable failure %drn", status);
        return;
    }
}

void CyCx3ImuIntDisable(void)
{
    CyU3PGpioSimpleConfig_t gpioConf;
    CyU3PReturnStatus_t status = CY_U3P_SUCCESS;
    /* Configure CLOVER_IMU_INT pin*/
    gpioConf.outValue = CyFalse;
    gpioConf.driveLowEn = CyFalse;
    gpioConf.driveHighEn = CyFalse;
    gpioConf.inputEn = CyFalse;
    gpioConf.intrMode = CY_U3P_GPIO_NO_INTR;
    status = CyU3PGpioSetSimpleConfig(CLOVER_IMU_INT,  gpioConf);
    if (status != CY_U3P_SUCCESS)
    {
        Cx3Err("[GPIO] imu interrupt pin disable failure %drn", status);
        return;
    }
}

CyU3PGpioSetSimpleConfig  返回值为0x44 CY_U3P_ERROR_NOT_CONFIGURED
