TDA4VE-Q1: How to choose Main domain SMI or MCU domain SMI to connect external ethernet switch SMI interface?

如我们所知，SoC芯片TDA4VE内部含Main域和MCU域，当前我不知道外部的以太网交换机SMI(MDC, MDIO)端口是连接到SoC的Main域还是MCU域的SMI端口，同时，SoC与外部的以太网交换机之间的中断(nINT)信号，复位(nRST)信号是连接到SoC的Main域还是MCU域的GPIO口呢？选择不同的域是否会涉及到对软件的影响？期待TI专家们的回复，谢谢！

As we know, the SoC TDA4VE has main domain and MCU domain, currently, I don't know how to choose Main domain SMI or MCU domain SMI to connect external ethernet switch SMI ports, and also for the nINT and nRST signals between TDA4VE and external ethernet switch. Will any software impact for the domain selection ? Hope TI expert can provide me proposals, thank you in advance.

Main域和MCU域都有MDIO，看您交换机接的是哪个管脚。请看下面数据手册上管脚说明。6.3.9 MDIOhttps://www.ti.com/lit/ds/symlink/tda4ve-q1.pdf
