W6100 1V2O voltage

TCP/IP Chip W6100

Hello,
I am going to use W6100 for spi communication with my microcontroller.
Is pin 14, 1V2O , on w6100 output. Do I have to use external voltage regulator , for example input 3.3V output 1.2V, or I should use 1V2O to supply other power pins as 1V2A and 1V2D.
I have not notice external voltage regulator with 1.2V output on W6100 evaluation board.
Thanks

This is the schematic of WIZ610io and it makes for SPI communication with MCU.
Please keep that in mind.
If that doesn’t work, I’ll forward the issue to a hardware engineer.
