Hi TI support engineer:
We are to revise to a new board of Des.914Q (DS90UB914Q), which the last version did not work somehow. Now we have a confusion regarding the datasheet saying input pins PDB ,BISTEN., OEN, OSS_SEL and SEL "have internal PULL DOWN" (datasheet page 7)", However , from the EVL board it looks like these are PULL UP not DOWN. Please advise if it is PULL UP OR PULL DONWN? and what are these internal resistors' value anyway?
See attached picture
