Short Desc. : AU-UB7311: USB 1.1 Device AMBA Subsystem Core
Overview :
The AU-UB7311 USB 1.1 Device AMBA Subsystem provides a USB 1.1 Device peripheral
subsystem for AMBA based SOCs. It contains a USB 1.1 Device that connects seamlessly to the AMBA AHB Bus. It includes the required USB endpoints plus eight bulk/iso transfer endpoints. A DMA Engine is included to move bulk and isochronous USB data.
Features : - USB 1.1 Device
- Ten endpoints:
- EP0- control endpoint, accepts SETUP, IN, and OUT control transactions
- EP1- interrupt endpoint, accepts IN and OUT interrupt transactions
- EP2, EP4, EP6, EP8- IN endpoints; accept IN bulk and isochronous
- transactions
- EP3, EP5, EP7, EP9- OUT endpoints; accept OUT bulk and isochronous
- transactions
- Serial interface to PHY transceiver chip
- Accepts stalls from the application logic
- DMA/AMBA Interface
- AMBA AHB Bus interface
- 8 channel DMA Engine
- bulk/iso IN data from each bulk/iso IN endpoint to the USB 1.1 Device block
- bulk/iso OUT data from the USB 1.1 Device block to each bulk/iso OUT
- endpoint
- Physical DMA addresses
- Programmable DMA starting address
- Programmable DMA transfer count- up to 64 Kbytes
- Programmable DMA AMBA Bus interface transaction size- 8 to 1024 bytes
- Programmable DMA AMBA Bus data transfer size- 4 or 8 bytes
- Locked DMA operation optional (software programmable)
- Direct software writes or information extracted from descriptors in memory, to
- program DMA control information
- Dedicated AMBA Bus master interface for each DMA channel
- AMBA Bus slave interface for register reads and writes
- Interrupts:
- DMA completed
- IN transaction data sent
- OUT transaction data received
