Title: End of packet in USB data and token packets
Post by: titan_amit on June 05, 2011, 06:06:19 am

I was going through standard USB packet structure where i found that EoP was given in terms of time. I didn't get how is this possible. Please if some body can explain how to implement that.

Well, more accurately, bit times:
     "SE0 for approximately 2 bit times followed by a J for 1 bit time."

Which part of that do you find difficult to picture?

(Usually the SIE will deal with this for you, of course.)
