VCC-IO,VCC-PC => 3.3V
VCC-PD,VCC-PE => 2.5V
VCC-PG,VCC-PL => 1.8V

(although I didn't check with voltmeter yet)

martinayotte,  thank you for this note;  the question now is the reverse, what are the maximum voltages for these pins on input ?!?   Is the maximum 3v3 on all GPIO pins, or is it (for instance)  1.8v on  PG, and PL ?

Wish we had the latest schematic and datasheet for the 2G A64 +
marcushh777    Cool
