Description of Pipes
For the USB controller 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.
In host mode, the USB controller associates a pipe to a device endpoint, considering the device
configuration descriptors.
Figure 30-23
After a hardware reset, the USB controller host mode is in the Reset state.
When the USB macro is enabled (USBE = 1) in host mode (ID = 0), its host mode state goes to
the Idle state. In this state, the controller waits for device connection with minimal power con-
sumption. The USB pad should be in the Idle state. Once a device is connected, the macro
enters the Ready state, what does not require the USB clock to be activated.
