Endpoint 0
Endpoint 0 is the AT43312A’s default endpoint used for enumeration of the Hub and
exchange of configuration information and requests between the Host and the
AT43312A. Endpoint 0 supports control transfers.
The Hub Controller supports the following descriptors: Device Descriptor, Configuration
Descriptor, Interface Descriptor, Endpoint Descriptor, and Hub Descriptor. These
Descriptors are described in detail elsewhere in this document. Standard USB Device
Requests and class-specific Hub Requests are also supported through Endpoint 0.
There is no endpoint descriptor for Endpoint0.
Endpoint 1
Endpoint1, an interrupt endpoint, is used by the Hub Controller to send status change
information to the Host. The Hub Controller samples the changes at the end of every
frame at time marker EOF2 in preparation for a potential data transfer in the subsequent
frame. The sampled information is stored in a byte wide register, the Status Change
Register, using a bitmap scheme.
Each bit in the Status Change Register corresponds to one port as shown on the follow-
ing page.
