USB High-Speed On-the-Go Host Device Controller
31.1 USB High-Speed OTG-capable USB Controller Overview
The
i.MX28 has two USB high-speed controllers, the first one is a OTG-capable USB high
speed controller(a.k.a USB0), and the second one is host-only high-speed USB
controller(a.k.a USB1). This chapter describes the USB high-speed OTG-capable
controller(USB0) included on the i.MX28. The host-only high-speed USB controller(USB1)
is a subset of the OTG-capable controller(USB0). This chapter includes sections on the
PIO, DMA, and UTMI interfaces, along with USB controller flowcharts.
The i.MX28 includes a Universal Serial Bus (USB) version 2.0 controller capable of
operating as either a USB device or a USB host, as shown in
Figure
31-1. In addition, USB0
contains supporting circuitry for USB On-the-Go (OTG). USB1 is configured as host-only
controller. The USB controller is used to download digital music data or program code into
external memory and to upload voice recordings from memory to the PC. Program updates
can also be loaded into the flash memory area using the USB interface.
As a host controller, it can enumerate and control USB devices attached to it. The USB
controller included on the i.MX28 supports eight endpoints: one control, one bulk-out, one
bulk-in, and five flexible endpoints. Using the OTG features, the USB controller can negotiate
with another OTG system to be either the host or the device in a peer connection.
The USB controller operates either in full-speed mode or high-speed mode.
Refer to the USB Implementer's Forum website www.usb.org for detailed specifications
and information on the USB protocol, timing and electrical characteristics.
The USB 2.0 controller comprises both a programmed I/O (PIO) interface and a DMA
interface. Both of these interfaces are designed to meet an ARM Ltd. AMBA Hardware
Bus (AHB). The AHB is used by the USB controller as a slave (PIO register accesses) and
as a master (DMA memory accesses).
