RGMII I/O supply mode setting

Dear Sir

 

I refer to the IMX6SXIEC Rev. 3.

It has four voltage mode (1.5, 1.8, 2.5 and 3.3V) for RGMII I/O supply.

 

Q1.

Is it necessary to set some register in order to set the voltage mode?

I think that it is only to use within the range of min = 1.43 V, Typ = 1.5 V, max = 1.58 when we want to use it in 1.5V mode.

Is my understanding correct?

Best Regards,

Eishi SHIBUSAWA
