DS90UB933-Q1: Can GPO0 pin be pulled up when power up

Part Number: DS90UB933-Q1

Hi team,

My customer used DS90UB933-Q1, they want to pull up GPO0 pin when power up to shorten the initialization. Can you please help double check if there will be any risk? And what is the voltage level if pulled up? Can you please help share the GPO inner structure? Thanks.

BR,

Rory

    Rory,

    Sorry, I can't understand why you link the "short initialization" with "GPO0".

    For 933/934 link, it can work automatically after the power-up without register setting request (you need select the correct mode in mode_sel pins), this is TI's selling points in the market.

    regards,

    Steven
