Data flow on
USB cable
Note: While register accesses required for each request are made to UDC2 between 'Issuing the "Setup_Received"

Figure 3.16.20 Flow of control in Control-WR transfers (without DATA-Stage)
(2) Control-WR transfer (without DATA-Stage)
command' and 'Issuing the "Setup_Fin" command', register accesses are needed after the end of
STATUS-Stage in some cases such as Set Address request and Set Feature (TEST_MODE). Processes
required for the standard requests are described in (5).
After issuing the “Setup_Received” command, make register accesses to UDC2 based
on each request. Issue the “Setup_Fin” command when all the register accesses to
UDC2 have finished. Subsequent processes are basically the same as the
STATUS-Stage described in (1). UDC2 will keep on returning “NAK” until the
“Setup_Fin” command is issued.
