There are two occasions where the device controller may need to return to the host a
STALL:
Remark: Any write to the ENDPTCTRLx register during operational mode must preserve
the endpoint type field (i.e. perform a read-modify-write).
Table 348. Device controller stall response matrix
Data toggle is a mechanism to maintain data coherency between host and device for any
given data pipe. For more information on data toggle, refer to the USB 2.0 specification.
The DCD may reset the data toggle state bit and cause the data toggle sequence to reset
in the device controller by writing a ‘1’ to the data toggle reset bit in the ENDPTCTRLx
register. This should only be necessary when configuring/initializing an endpoint or
returning from a STALL condition.
Remark: This feature is for test purposes only and should never be used during normal
device controller operation.

2. A protocol stall, unlike a function stall, is used on control endpoints is automatically
described in the USB 2.0 device framework (chapter 9). A functional stall is only used
on non-control endpoints and can be enabled in the device controller by setting the
endpoint stall bit in the ENDPTCTRLx register associated with the given endpoint and
the given direction. In a functional stall condition, the device controller will continue to
return STALL responses to all transactions occurring on the respective endpoint and
direction until the endpoint stall bit is cleared by the DCD.
cleared by the device controller at the start of a new control transaction (setup phase).
When enabling a protocol stall, the DCD should enable the stall bits (both directions)
as a pair. A single write to the ENDPTCTRLx register can ensure that both stall bits
are set at the same instant.
