    manual mode endpoint and slave fifo




      I have a FX2LP configured in slave fifo (with an external device that is reading data). I have endpoint 2 and 4 configured as bulk endpoint in manual mode, with buffered 2x of 512 byte length.


      I would know if when 8051's FX2LP is accessing fifo data - before commit packet - is a safe practice, even if external device is reading data from slave fifo. 8051 checks fifo empty flag before accessdata,  and external device checks hardware empty flag before read data from slave fifo.


      What is the point of view of Cypress? Is there something to do for safety?


      Best Regards
