SPEAR-09-B042
8.7
USB2 device controller
The USB2 device controller provides the following features:
●
Supports the 480 Mbps high-speed mode (HS) for USB 2.0, as well as the 12 Mbps
full-speed (FS) and the low-speed (LS modes) for USB 1.1
●
Supports 16 physical endpoints and configurations to achieve logical endpoints
●
Integrated USB transceiver (PHY)
●
Local FIFO having size of 4 Kbyte shared among all the endpoints
●
DMA mode and slave-only mode are supported
●
In DMA mode, the UDC supports descriptor-based memory structures in application
memory
●
In both modes, an AHB slave is provided by UDC-AHB, acting as programming
interface to access to memory-mapped control and status registers (CSRs)
●
An AHB master for data transfer to system memory is provided, supporting 8, 16, and
32-bit wide data transactions on the AHB bus
●
A USB plug detect (UPD) which detects the connection of a cable
8.8
32-Kbyte boot ROM
The code contained in this ROM is executed at the boot time. It initializes the system and
can then boot from the serial Flash trough the SMI or from the USB device interface. To use
the latter possibility a suitable driver should be installed on the host platform.
