UCD90320: Sequence for GPI

HSU HANWEN

Part Number: UCD90320

Hi Yihe:

Is there any sequence requirement for UCD90320?

GPI ramp up with reset of UCD90320, do you have any concern on it?

*blue and purple are GPI, yellow is reset

GPI by default is HI-Z state. Do you have external pull-up on those signas?

No, that's the normal if you have a external Pull-up.
