19.1 Buffer Descriptor Table
DS0200-003
The USB controller is an AHB controller that can be configured as either a host or device and supports the
On-The-Go protocol. Features:
A Buffer Descriptor Table (BDT) in system memory manages USB endpoint communications. It resides on a
512-byte boundary pointed to by the BDT Page Registers. Every endpoint direction has two eight-byte
entries, allowing software to process one descriptor while hardware is processing the other descriptor.
Software manages buffers by updating the BDT. A semaphore mechanism is used to distinguish who is
allowed to update the BDT. OWN is cleared when the descriptor entry is owned by software, and set when
owned by the controller. The descriptor also contains pointers to where the data buffer resides in system
memory. The buffer descriptor provides endpoint control information for the controller and software. The
controller uses the descriptor to determine:
Software uses the data stored in the BDs to determine:
The format for the Buffer Descriptor is shown in Figure 19-1.
