/**
* FUSB302_UFP.h
*
* Updated on: Jan 4, 2021
* Author: Ryan Ma
*
* Minimalist USB PD implement with only UFP(device) functionality
* Requires only stdint.h and string.h
* No use of bit-field for better cross-platform compatibility
*
* FUSB302 can support PD3.0 with limitations and workarounds
* - Do not have enough FIFO for unchunked message, use chunked message instead
* - VBUS sense low threshold at 4V, disable vbus_sense if request PPS below 4V
*
