Receive Error.

 

 

 

 

 

RERR indicates that the current packet is in

 

 

 

 

 

error. RERR is only asserted when REOP is

 

 

 

 

 

asserted. Conditions that can cause RERR

 

 

 

 

 

to be set include FIFO overflow, CRC error,

 

 

 

 

 

code error, and runt or giant packets.

 

 

 

 

 

NOTE: RERR can only be set for these

Receive Data Valid.

 

 

 

 

 

RVAL indicates the validity of the receive

 

 

 

 

 

data signals. RVAL is Low between

 

 

 

 

 

transfers and assertion of RSX. It is also

 

 

 

 

 

Low when the IXF1104 MAC pauses a

 

 

 

 

 

transfer due to an empty receive FIFO.

 

 

 

 

 

When a transfer is paused by holding RENB

 

 

 

 

 

High, RVAL holds its value unchanged,
