USB Hub
A block diagram of the USB hardware of the AT43USB326 is shown in Figure 3. The USB hub
of the AT43USB326 has 3 downstream ports. The embedded function is permanently attached
to Port 1. Ports 2 and 3 are available as external ports. The actual number of ports used is
strictly defined by the firmware of the AT43USB326 and can vary from 0 to 2. Because the
exact configuration is defined by firmware, ports 2 and 3 may even function as permanently
attached ports as long as the Hub Descriptor identifies them as such.
USB Function
The embedded USB function has its own device address and has a default endpoint plus 2
other programmable endpoints with their own 8-byte FIFOs. Endpoints 1 and 2 can be pro-
grammed as interrupt IN or OUT or bulk IN or OUT endpoints.
