Endpoint 1 Buffer Reset in EZ-USB® FX2LP™ - KBA88218

Version: **

 

Question: Is it possible to reset the endpoint 1 buffers the same way as the other endpoint buffers (2, 4, 6, and 8) in EZ-USB® FX2LP™?

 

Answer:

Unlike the other endpoint buffers - that is, endpoint 2,4,6,8 buffers, which can be reset by the FIFORESET register - the only way to reset an endpoint 1 buffer is by a hard reset. A USB bus reset or a CPU reset does not reset the endpoint 1 buffer.
