Default

 

 

 

 

 

 

MAC threshold for TX FIFO Port 0. The

 

 

 

 

default value of 0x1BE represents 446 8-byte

 

 

 

 

locations. This equates to 3568 bytes of data. A

 

 

 

 

unit entry in this register equates to 8 bytes of

 

 

 

 

data. When the amount of data stored in the TX

 

 

 

TX FIFO MAC

FIFO reaches this threshold, data is forwarded

0x614

R/W

0x000001BE

Threshold Port 0

to the MAC core and line-side interfaces for

 

 

 

 

onward transmission. By setting the threshold to

 

 

 

 

an appropriate value, the user can configure the

 

 

 

 

TX FIFO to operate in a “cut-through” mode

 

 

 

 

rather than the default “store and forward”

 

 

 

 

operation mode.

locations. This equates to 3568 bytes of data. A

 

 

 

 

unit entry in this register equates to 8 bytes of

data. When the amount of data stored in the TX

 

 

 

FIFO reaches this threshold, data is forwarded

0x616

0x000001BE

Threshold Port 2

to the MAC core and line-side interfaces for
