USB Controller -- Doubts

Hello All,

In Jetson Tx2, In TRM, in section 32.6.1 USB PADCTL Features,

Battery Charging

  • Supports standard and charging downstream port identification control when programmed as host/downstream
  • Supports charging port detection reporting as when programmed device/upstream ports

What is the meaning of this? I need some more details to get the idea on this.


It is the literal meaning.
