Figure 32-10. Control Read
A NAK handshake is always generated as the first status stage command. The UESTAn.NAKINI
bit is set. It allows the user to know that the host aborts the IN data stage. As a consequence,
the user should stop processing the IN data stage and should prepare to receive the OUT status
stage by checking the UESTAn.RXOUTI bit.
The OUT retry is always ACKed. This OUT reception sets RXOUTI. Handle this with the follow-
ing software algorithm:
Once the OUT status stage has been received, the USBC waits for a SETUP request. The
SETUP request has priority over all other requests and will be ACKed.
// process the IN data stage
set TXINI
wait for RXOUTI (rising) OR TXINI (falling)
if RXOUTI is high, then process the OUT status stage
if TXINI is low, then return to process the IN data stage
