Notes
Read Cycle
EXTFIFO = HIGH
FIFOBYP = HIGH
36. When reading data from synchronous data interface, the data is captured on any clock cycle that RXEN = LOW. RXEMPTY = HIGH indicates data is available.
37. Illustrates timing only. RXEN and RXRST not usually active in same time period.
38. Receive FIFO Reads are inhibited while the outputs are High-Z.
