Use the Triple Speed Ethernet megafunction. I checked the MDIO option to control the PHY, but the data line is instantiated as two signals, input and output, instead of bidirectional signals. How can I use it as MDIO?

Use the Triple Speed Ethernet megafunction. I checked the MDIO option to control the PHY, but the data line is instantiated as two signals, input and output, instead of bi-directional. How can I use it as MDIO?

Enabling the MDIO option on Triple Speed Ethernet (TSE) generates an output enable signal for MDIO.
This is achieved by preparing a tri-state buffer outside the TSE and using the output enable signal to switch between input and output.
