USB Device Operation
Introduction
Power-On and Reset
USB Reset
In device mode, the USB controller supports full- and low-speed data transfers.
In addition to the default control endpoint, six endpoints are provided, which can be configured
with the types isochronous, bulk or interrupt, as described in
The device mode starts in the Idle state, so the pad consumption is reduced to the minimum.
Figure 30-13
After a hardware reset, the USB controller device mode is in the Reset state. In this state:
D+ or D- will be pulled up according to the selected speed as soon as the DETACH bit is cleared
and VBus is present. See
When the USB macro is enabled (USBE = 1) in device mode (ID = 1), its device mode state
goes to the Idle state with minimal power consumption. This does not require the USB clock to
be activated.
The USB controller device mode can be disabled and reset at any time by disabling the USB
macro (USBE = 0) or when host mode is engaged (ID = 0).
The USB bus reset is managed by hardware. It is initiated by a connected host.
When a USB reset is detected on the USB line, the following operations are performed by the
controller:
•the macro clock is stopped in order to minimize power consumption (FRZCLK = 1);
•the internal registers of the device mode are reset;
•the endpoint banks are de-allocated;
•neither D+ nor D- is pulled up (DETACH = 1).
•all the endpoints are disabled, except the default control endpoint;
•the default control endpoint is reset (see
•the data toggle sequence of the default control endpoint is cleared;
•at the end of the reset process, the End of Reset interrupt (EORST) is raised.
