About VDD_SEL of DS80PCI102 datasheet, writing by P4 and P14 differ.

・Page4 ： Tie GND = 3.3V mode
・Page14 ： Tie VDD_SEL = 0 with 1K resistor to GND.

Which is right?

（I think OK by both.）

Hi Satoshi-san,

Both ways are acceptable. Since this pin only has two states (Float and Low), all that matters is that the pin is pulled low to GND to activate 3.3 V mode.

Thanks,

Michael
