Hi, Team,

Please let me the pin linked with VDDIO(pin which becomes 1.8V I/O) when 1.8V is applied to DDIO(pin 19).

Hi Satoshi-san,

All the pins except power, MDI and LED_0 will be linked to VDDIO voltage levels: for example: RESET, Interrupt, MAC interface.

LED_0 is always tied to 3V3 AVDD.

Hi Satosh-san,

You need to add MDIO ( Pin 15). Rest covers all.
