DRA821U: Why are there two identical muxmode functions for the same pin?

Why are there two identical muxmode functions for the same pin?

Nancy Wang：

我需要确认一下再给您回复，似乎只有RMII1相关的引脚是这样的。

nono li：

MCAN的引脚也同样似的设计，我暂时还没在TRM中找到这样设计的用意

Nancy Wang：

我们正在确认，晚点给您回复。

请先参考以下帖子中的回复：

nono li：

Thanks for the reply, now I know that their function exactly the same.But im still curious about the purpose of this design. Is it for the convenience of register configuration , to make the code more consise?Any insights will be helpful.

Nancy Wang：

我还在等待答复，晚些给您回复。

Nancy Wang：

没有得到很明确的回复。

请参考：

It does seem redundant but it provides the option to use the pins with either of the pin mux settings.
