Hi,

 

I havea question about ENET MII mode.

In MII mode, these  ENET_REF_CLK(ENET_TX_CLK) and GPIO18(ENET_RX_CLK) are for clock. 

Both pins are input pins?

 

I read Reference manual but I'm not sure below.

Reference Manual described

*IOMUXC_SW_MUX_CTL_PAD_ENET_REF_CLK

001 ALT1 — Select signal ENET_TX_CLK. In MII mode, provides a timing reference for TX_EN, 

 

*IOMUXC_SW_MUX_CTL_PAD_GPIO18

001 ALT1 — Select signal ENET_RX_CLK.
- Configure register IOMUXC_ENET_MAC0_RX_CLK_SELECT_INPUT for mode ALT1.

 

Best Regards,

Sugiyama
