PHY layer flow control. 1= Xon, 0= Xoff. Asserted
by the PHY layer for normal transmission.
Deasserted by the PHY layer when the ATM link is
experiencing congestion. The response of the
ATM layer to this signal is user defined. Not Used.
Active low transmit signal asserted by the ATM
layer during cycles when the TxDat contains valid
cell data.

RxDat[7:0] corresponds to a cell byte. Please refer
to the S/UNI datasheet for the byte cell data
structure.
RxDat[7] corresponds to bit 1, the first bit received.
RxDat[0] corresponds to bit 8, the last bit received.
Receive data bus (RxDat[7:0]) odd parity. Not

Ground
Receive start of cell indication. Identifies the first
byte (word) of a cell on outputs RxDat[7:0]
Ground
Ground
Active low empty signal to indicate that in the
current cycle there is no valid data for delivery to
the ATM layer.
