你好，我看MAC_ID0_LO连续四个寄存器说明是可读可写的，这样用户就可以修改了？
另外这8个寄存器
#define DM81XX_ID_W0 (0x48141844)
#define DM81XX_ID_W1 (0x48141828)
#define DM81XX_ID_W2 (0x4814182C)
#define DM81XX_ID_W3 (0x4814184C)
#define DM81XX_ID_R0 (0x4814183C)
#define DM81XX_ID_R1 (0x48141848)
#define DM81XX_ID_R2 (0x48141824)
#define DM81XX_ID_R3 (0x48141850)
有相关说明文档吗？谢谢！
