(11) VALID (Setup Packet Detect) Bit (b3)
SET _CO NFIG URAT IO N excecution[ConfigurationValue=0]
This bit indicates that the setup token has been received.
When the setup token is completely received, this bit is set to “1”.
When this bit is set to “1”, the writing to EP0_PID/CCPL bits of EP0_FIFO Control Register is ignored.
At the time of receiving the setup token, the interrupt has not occurred (the interrupt occurs only after the
termination of setup stage).
This bit is cleared to “0” by writing “0”.

(W hen URST bit="1", DVST bit is set to "1")
Note : The URST , SADR, SCFG and SUSP bits (Interrupt Enable Register 0) in the parenthesis set enable/disable to set the DVST bit to "1" for the
(
W hen SCFG bit="1", DVST bit is set to "1")
corresponding stage transition. There is no bit to set enable/disable to set the RESM bit to "1".
The stage transition takes place even if these bits are inhibited to set to "1".
