68013A: EP6 not full and not empty after startup.
I have 68013A chip configured as slave fifo. After i download a firmware I see that enumeration occurs. Than I'm trying to perform the asynchronous write. I select the EP6 endpoint and i see that FLAFB and FLAGC are both high (+3.3V). As FLAG pins are configured as active low that means that EP6 edpoint is not empty and not full.
What that supposed to mean? I didn't performed any write operations to that endpoint.
