    3 questions about SLAVE FIFO AUTO IN

    @zju.edu.cn.2
              1,If CY7C68013's slave fifo selects the internal 48MHZ clock, what is the requirements for the SLWR signal in asynchronous bulk transfer?##################### 2,what is the time delay since the FIFO empty untill EF flag active?##################### 3,In my slave fifo auto-in bulk transfer,after the firmware downloading,the EF and FF are low(active high).##################################################### I use the CYConsole to test the transfer. I find the first packet 512 bytes bulk transfer successfully without writting datum, but the transfer have no data, it displays " bulk in transfer bulk in successfully 0x0000". however, the second bulk transfer would be failed, it will display "bulk in tranfer , bulk in failed" .########################################### when I write data in fifo,the first packet data would still be some dummy bytes,it also displays " bulk in transfer bulk in successfully 0x0000".but the successive packets are right.####Idon't konw why?
