HDLC 标准库函数报错问题

编译显示：

        RCCU_PCLKConfig(RCCU_Div_2);              //PCLK2=24MHz APB2 periph

部分报错函数程序如下：

HDLC_Init_Xmit(HDLC_NRZ);                  //NRZ coding used

//Set up Receiver
HDLC_Init_Recv(HDLC_PAE | HDLC_R_NRZ);

标准库函数如下定义如下：
void HDLC_Init_Xmit(HDLC_TCTL_Flags Flags);
void HDLC_Init_Recv(HDLC_RCTL_Flags Flags)；

HDLC_NRZ定义为HDLC_TCOD_ENC枚举类型

HDLC_PAE定义为HDLC_RCTL_Flags枚举类型
HDLC_R_NRZ定义为HDLC_RCOD_ENC枚举类型
这些都是标准库函数，，程序也是官方提供的函数没做任何修改，，

请问这影不影响程序正常工作，，或者改怎么修改

正点原子

帮顶。。。。。
