Receive Data Interface Timing (cont’d)
8.01 Receive Data Interface Read Timing 1
Notes:
1. SPDTAVL gets deasserted because of the 7th double word read from the receive FIFO indicating that there is
no more data available in the receive FIFO and further reads will cause invalid reads. Here, it is important to note
that the 7th read is referred to the 7th clock edge that latches in the active low RXRDEN and the resultant data
can be latched out on the 8th clock edge because of the pipelining effect.
