Description
Transmit FIFO Ready Output.
These outputs, one per port, indicate
that the TX FIFO space exceeds the programmable threshold value.
These outputs are clocked out on rising edges of the system clock, SCLK,
and are put in high impedance state when TXINTEN is deasserted.
1 = TX FIFO Space
≥
TX FIFO Threshold
0 = Below Threshold
FIFO Space/Data Available Output.

For RX FIFO Reads:
1 = More than 1 Double Word of Data in RX FIFO
0 = Data Not Available
For TX FIFO Writes:
1 = More than 2 Double Words of TX FIFO Space Available
0 = Space Not Available
This output is clocked out on rising edges of the system clock, SCLK,
and is for the selected port.
Receive FIFO Overflow Output.

These outputs, one per port, are clocked out on rising edges of the
system clock, SCLK .
Receive-Transmit End of Frame Input/Output.
This bidirectional pin
indicates that the current data word, for the selected port, is the last
double word of the packet. During receive FIFO reads, this pin is an
output and is asserted active high when the last word of a receive packet
is being read out of the receive FIFO on RXTXDATA[31:0]. During
transmit writes, this pin is an input and needs to be asserted active high
when the last word of the packet is being written into the transmit FIFO
on RXTXDATA[31:0]. This signal is clocked in/out on rising edges of
the system clock, SCLK.
Transmit No CRC Input.

This input is clocked in on rising edges of the system clock, SCLK, and
is for the selected port.
