Bit

Name

Function

15

x

Ignored by adapter. The value in this bit is a don't care.

14Frm_Cmp 0 Frame complete: Ignored by adapter. Should be set to 0. Setting the Frm_Cmp bit to 0 is good programming practice.

13

1

Ignored by adapter. Set to 1

12

1

Ignored by adapter. Set to 1

11

0

Ignored by adapter. Set to 0

10

0

Ignored by adapter. Set to 0

9

Pass_CRC

Pass CRC: When this bit is set to a 1, the adapter uses the last four bytes of frame data

 

 

as the frames CRC. The integrity of this CRC is not checked and it is handled just like

 

 

the data payload. If this bit is set to a 0, CRC is generated by the adapter as normal.

8

0

Ignored by adapter. Should be set to 0

7±3

Reserved

This field is Ignored by the adapter, but should be set to 0.

2±0

Network

Network priority request: Indicates the network transmission priority to be used for the

 

priority

frame when network protocol types 2 or 3 are selected. The value in this field is passed

 

 

to the external protocol engine across the 802.3u MII on the MTXD[3::1] signal lines dur-

 

 

ing transmission requests.

This field has no meaning if network protocol types other than 2 or 3 are selected.
