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.



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,
