Hi, is it possible to set the VDD_GPO to 1.8V to have 1.8V logic high level at the GPO pins? The datasheet mentions only 3.3V in the text and the FMCOMMS3 reference board does not have a straight forward option to change from 3.3V to 1.8V GPO logic.


It is mentioned though in Table 1, that the minimum voltage on VDD_GPO is 1.3V and maximum is 3.3V, but no typical voltage is set.
