11.1.1 Features
11.1 Introduction
11.2 Overview
The Universal Serial Bus (USB) Host Controller enables communication to USB 2.0 low-
speed (1.2 Mbps) and full-speed (12 Mbps) devices. The controller supports three root hub
ports and complies with the Open Host Controller Interface (OpenHCI) specification, version
1.0a. (For additional information, see
The features of the USB Host Controller are:
The USB Host Controller is partitioned into the key sub blocks as indicated in
