T1042 Power Design

Hi,

I design a board with T1042 processor, In this board, I must use from MII with 3.3volt power and RGMII with 2.5volt power  for MAC interfaces.In T1042 processor, EC1 use L1VDD power and EC2 use LVDD power. In T1042 datasheet say "Selecting RGMII limits L1VDD and LVDD = 1.8 V or 2.5 V. L1VDD and LVDD should be configured at same voltage."

 

If I use from 3.3volt for L1VDD and 2.5volt for LVDD, does T1042 work good? What problem maybe occured in T1042 working?

thanks
