Transmit Path Signals
Active high outputs, Transmit Port Select [2:0].
Active Low, output.
Transmit Device Selects [1:0].
Active High, output. TXASIS states are output according to values programmed in
the TFIFO Control field. TXASIS state is output coincident with SOP32 signal.
Active Low, output, byte enables for FDAT [63:31].
Active High, output, 32-bit transmit data.
Active High, output.
Receive Port Selects [2:0].
Active Low, output.
Receive Device Selects [1:0].
Active High, input/output. Driven as output when bus remains in No-Select state.
Active High, input/output. Driven as output when bus remains in No-Select state.
Active High, input/output, input Receive Error indication from the MAC. Driven as
output when bus remains in No-Select state.
Active Low, input/output, input byte enables for FDAT [31:0] from the MAC. Driven
as output when bus remains in No-Select state.
Active High, input/output, input 32-bit receive data from the MAC. Driven as output
when bus remains in No-Select state.
Active Low, output, flow-control for MAC 0.
Active Low, output, flow-control for MAC 1.
Active Low enable outputs for Transmit or Receive Ready flags.
Active High, input/output, Transmit or Receive Ready flags, and flow control mask
data.
Input, not used, must be pulled High in this mode.
Output, not used, no connect.
Active High, ready input from Fast Port 0, pulldown 10 KOhms if not used.
Active High, ready input from Fast Port 1, pulldown 10 KOhms if not used.
