Q1:I get "When AUTOOUT=1, as soon as a buffer fills with USB data, the buffer is automatically and
instantaneously committed to the endpoint FIFO bypassing the CPU" from FX2 TRM,can you give me more details about the differences and relations between endpoint FIFO and buffer, and how about is it in AUTOIN? 

Q2:The state of EF,FF,(PF) is given in EP2468STAT and EP24FIFOFLGS,and the state of EF,FF and PF can also be expressed by flagA(or flagB flagC). The states all above are identical ?

thank you!
