USB-TO-GPIO2: Pin 7 Status Variation compare with 2006/22 Version

Hi Team,

About USB-TO-GPIO2:

1. I notice no matter in 2006 or 2022 version, pin 7 are always HIGH(default), could you check this part again?

Customer only connected the PC and USB adapter to the 2006 version, measured pin 7 of the connector from adapter, and observed a low level....

Which didn't match what documentation had mentioned. 

2022

2. In the 2006 version schematic there are no pull up circuits. Might it be necessary to configure the internal chip to pulled high this pin(Pin 7)?
