RT1176 ENET_QOS RMII连接问题

[Vincent_11_CWS]

问题：我们想使用RT1176 ENET_QOS的RMII模式来连接PHY，其中PHY上的RMII_CRS_DV这个引脚应该与RT1176 ENET_QOS的哪个引脚相连呢？在RT1176的datasheet和参考设计中都有描述，如果使用ENET/ENET1G的话，RMII_CRS_DV可以连接到RX_EN上，但是关于ENET_QOS并没有这样的描述，我们该如何设计呢？

Would be possible that you put your question in English?

I have some questions regarding NXP RT1176, which would need your clarifications. When we apply the RMII mode of RT1176- ENET_QOS, which pin should CRS_DV in PHY connect to? According to the description in the datasheet, it would connect with RX_EN in ENET/ENET1G. However I can’t find any contents in ENET_QOS of RT1176.
