[参考译文] DP83TC812R-Q1：什么和#39；s 器件 DP83TC812_CS2_x_PHY_ID (DP83TC812RRHARQ1)的返回 ID

您好、专家

在标题说明中、我们研究了  DP83TC812R 驱动器、发现其中包含两个 PHY_ID 代码。

};

static const struct dp83812_init_reg dp83812_master_cs2_0_init[] = {
	{0x523, 0x0001},
	{0x81C, 0x0fe2},

	{0x03E, 0x0009},
	{0x01f, 0x4000},
	{0x523, 0x0000},
};

每个 ID 都有自己的初始化序列、有什么区别？

DP83TC812RRHARQ1是否返回"DP83TC812_CS1_0_PHY_ID"或"DP83TC812_CS2_0_PHY_ID"？

非常感谢
