USB2/USB3 Traffic to do a Read / Write
I am looking at converting my USB2 solution to this chip for my next design. I have a general question. With this new solution, if I want to a Async/Sync Write what types of USB traffic is required? Today I do a Control transaction to setup the addresses and then a bulk transaction to do the data transaction.
Could someone describe, using the current FW and PC Software driver supplied by Cypress, what USB packets are required to do the following.
1) A simple 32 Bit Write
2) A Simple 32 Bit Read
3) A 64K Byte Write
4)A 64K Byte Read
What type of USB Transaction Control, Interrupt or Bulk and what are the contents of the packets?
