24. USB host operating modes
This mode is available only on Atmel AT90USB647/1287 products.
24.1
Pipe description
For the USB Host controller, the term of Pipe is used instead of Endpoint for the USB Device
controller. A Host Pipe corresponds to a Device Endpoint, as described in the USB specification.
Figure 24-1. Pipes and endpoints in a USB system.
In the USB Host controller, a Pipe will be associated to a Device Endpoint, considering the
Device Configuration Descriptors.
24.2
Detach
The reset value of the DETACH bit is 1. Thus, the firmware has the responsibility of clearing this
bit before switching to the Host mode (HOST set).
24.3
Power-on and reset
Figure 24-2 explains the USB host controller main states on power-on.
