USB-B
port
The observed current depends on the existing system board connected to
a VSNK terminal on the EVK. The contracted current is the maximum
current capability of a source and it doesn't means the consuming current
by a sink (It is equal to both the EVK and a load).
A 5A cable is required if
an existing system board
consumes over 3A.
USB communication is
available with both
JP_USB1 and JP_USB2
if an existing system
board has USB Type-B.

Port
Short the terminals P each other and the terminal N each
other to support flipped case on the Type-C connection.
VBRDY can use for the start
timing of USB communication.
5V POL
Connects the VBUS on the
USB-B port from a 5V POL
