Access to the USB host operational registers is achieved through the ASB bus interface. The
Open HCI host controller initializes master DMA transfers with the ASB bus as follows:
Memory access errors (abort, misalignment) lead to an “UnrecoverableError” indicated by the
corresponding flag in the host controller operational registers.
All of the ASB memory map is accessible to the USB host master DMA. Thus there is no need to
define a dedicated physical memory area to the USB host.
The USB root hub is integrated in the USB host. Several USB downstream ports are available.
The number of downstream ports can be determined by the software driver reading the root
hub’s operational registers. Device connection is automatically detected by the USB host port
logic.
Warning: a pull-down must be connected to DP on the board. Otherwise The USB host will per-
manently detect a device connection on this port.
USB physical transceivers are integrated in the product and driven by the root hub’s ports.
Over current protection on ports can be activated by the USB host controller. Atmel’s standard
product does not dedicate pads to external over current protection.
