Device Mode
Host Mode
In peripheral mode, the UDINT.SUSP bit indicates that the usb line is in the suspend mode. In
this case, the USB Data transceiver is automatically set in suspend mode to reduce the
consumption.
When the USB interface is in device mode, the speed selection (full-/low-speed) depends on
which of D+ and D- is pulled up. The LS bit allows to connect an internal pull-up resistor either
on D+ (full-speed mode) or on D- (low-speed mode). The LS bit should be configured before
attaching the device, what can be done by clearing the DETACH bit.
When the USB interface is in host mode, internal pull-down resistors are connected on both D+
and D- and the interface detects the speed of the connected device, which is reflected by the
SPEED bit-field.
Pipes and endpoints can only be allocated in ascending order (from the pipe/endpoint 0 to the
last pipe/endpoint to be allocated). The firmware shall therefore configure them in the same
order.
The allocation of a pipe/endpoint k
cates a memory area in the DPRAM and inserts it between the k
