USB Host Operation
Description of pipes
Power-On and reset
For the USBB in host mode, the term “pipe” is used instead of “endpoint” (used in device mode).
A host pipe corresponds to a device endpoint, as described by the
from the USB specification.
Figure 26-21. USB Communication Flow
In host mode, the USBB associates a pipe to a device endpoint, considering the device configu-
ration descriptors.
Figure 26-22 on page 645
Figure 26-22. Host Mode States
After a hardware reset, the USBB host mode is in the Reset state.
When the USBB is enabled (USBE is one) in host mode (ID is zero), its host mode state goes to
the Idle state. In this state, the controller waits for device connection with minimal power con-
describes the USBB host mode main states.
