[3:0] to NAK IN-Status OUT mode (1110) after ACKing a valid
status stage OUT token. The firmware needs to update the mode
for the SIE to respond appropriately. See
on what modes will be changed by the SIE.
Any SETUP packet to an enabled endpoint with mode set to
accept SETUPs will be changed by the SIE to 0001 (NAKing).
Any mode set to accept a SETUP will send an ACK handshake
to a valid SETUP token.

A disabled endpoint will remain disabled until changed by
firmware, and all endpoints reset to the Disabled mode (0000).
Firmware normally enables the endpoint mode after a SetCon-
figuration request.
The control endpoint has three status bits for identifying the
token type received (SETUP, IN, or OUT), but the endpoint must
be placed in the correct mode to function as such. Non-control
endpoints should not be placed into modes that accept SETUPs.
