160 - USB-A to USB-C Development Board in VL16X Atmosphere

Preface: It's been a long time since I've worked on an open-source project. Due to studies and various other reasons, I've been very busy since entering university.
 
Module Introduction:
This is a development board for the VL160 and VL162 MUX chips. Almost all pins are exposed, and most functions are configurable.
 
Module Functions:
USB-A is used as a USB signal input, and the chip processes the signal to USB-C for USB output, supporting 10Gbps. USB 3.X Gen2
or USB-C as USB signal input and USB-A as USB output (but this is less common)
 
can be used in various docking stations. Generally, it can upgrade the docking station's DFP interface, with USB-A acting as a UFP, that is, as the "device/slave" end for data 
transmission. USB-C acts as the "host" end. After USB-A is plugged into a computer or embedded motherboard, USB-C (hereinafter referred to as TYPE-C) can be plugged into a device to support your CC cable (TYPE-C to TYPE-C data cable with TYPE-C male connectors on both sides) to connect your various devices, including mobile phones and hard drives
 
. The main purpose of this board is for learning. Because VL160 and VL162 can be configured with broadcast current capability on TYPE-C, and it is bidirectional, you can also use the TYPE-C port as an input, and after reversible insertion identification, output in reverse to the USB-A port, allowing the USB-A port to be plugged into the input of some docking stations (the term "reverse" is used here because the USB-A on this board is male; generally, USB-A flows from the cable to the board, but here the signal is extended from the board to the cable).
 
Module technical explanation:
Here I assume you have some understanding of TYPE-C. I plan to turn this technical article into a video and upload it to Bilibili.
The above shows VL16X (X refers to 0 or 2; VL161 does not support this because VL161 does not have a CC pin and cannot automatically handle the TYPE-C direction judgment logic) used as a UFP. 
The above diagram shows VL16X used as a DFP.
 
VL16X pin configuration diagram:
If CC-LOAD is "11", it is configured as a UFP; otherwise, it is a DFP.
VBUS IMAX INDECATION only takes effect in DFP mode, indicating that the current capability of the broadcast TYPE-C is
330uA corresponding to 3A for "10".
