USB 1.1 Host Controller (USBH)

6.30.1

Overview

This chip is equipped with a USB 1.1 Host Controller (USBH) that supports Open Host Controller

Interface (OpenHCI, OHCI) Specification, a register-level description of a host controller, to manage

the devices and data transfer of Universal Serial Bus (USB).

The USBH supports an integrated Root Hub with a USB port, a DMA for real-time data transfer

between system memory and USB bus, port power control and port over current detection.

The USBH is responsible for detecting the connect and disconnect of USB devices, managing data

transfer, collecting status and activity of USB bus, providing power control and detecting over current

of attached USB devices.
