Universal Serial Bus OTG Module
14.1 Introduction
The Universal Serial Bus (USB) is a serial bus standard for communicating between a
host controller and different types of devices. USB has become the standard connection
method for PCs, PDAs, and video games, and more recently has been used on power
cords. This is because USB can connect printers, keyboards, mice, game devices,
communication devices, storage devices, and custom devices. USB 2.0 full-speed allows
12-Mbps communication between the host controller and the device.
14.2 Features
14.3 USB operation modes
Device Mode
The USB is configured to respond to external host requests. In this mode the MCU has no
control of the USB bus. All the transfers are started by the Host controller that is also
providing the VBUS voltage. The DCD was designed to run together with this USB
mode. First, the DCD detects the host type and after the USB takes the control of the D+
and D- signals.
