I wish to know that the How the VDD_Interface voltage level will affect RX/TX DATA & Controls, SPI lines voltage levels?

If i connect the interface to LVDS 2.5 V , will all data lines, controls lines,GPO & SPI lines voltage would be 2.5V if i feed VDD_INTERFACE voltage as 2.5V?

I want to know how this voltage level will affect on IO lines voltage levels? If i use LVDS mode what could be the voltage level of all Data, Control & SPI lines.

Thanks for your support in advance.
