关于NUC130RC系列I2C用作从机的配置

NUC130RC1cn I2C用作从机，程序初始化如下:

void  NUCI2CInit(void)
{
   uint32_t u32data=0,states = 0;

states = DrvGPIO_InitFunction(E_FUNC_I2C0);
states = DrvI2C_Open(I2C_PORT0, 300000);

states = DrvI2C_SetAddress(I2C_PORT0, 0, PCF8594_ADDR, 0);
   states = DrvI2C_InstallCallback(I2C_PORT0, I2CFUNC, I2C0_Callback_Slave);

   states = DrvI2C_EnableInt(I2C_PORT0);
   DrvI2C_Ctrl(I2C_PORT0, 0, 0, 0, 1);
}

配置后，跟其他CPU通信，发现进不了I2C中断，请问上面的初始化代码有没有问题
