Description
Hard TEMAC Reset. This bit provides a means for resetting the TEMAC
component. This bit is self clearing.
31
HtRst
Read/Write
0 _{0 - normal operation, TEMAC not reset}
1 - initiate a reset of the TEMAC (both Ethernet interfaces)
Reject Receive Multicast Destination Address. This bit provides a
means for accepting or rejecting multicast Ethernet frames.
0 - accept receive multicast destination address Ethernet frames that meet
30
McstRej
Read/Write 0 address filtering specified in AFM register an/or the multicast address
table
1 - reject all receive multicast destination address Ethernet frames
regardless of AFM register and multicast address table
Reject Receive Broadcast Destination Address. This bit provides a
means for accepting or rejecting broadcast Ethernet frames.
0 - accept receive broadcast destination address Ethernet frames
29
BcstRej
Read/Write
0
1 - reject all receive broadcast destination address Ethernet frames. This
is the only method available for blocking broadcast Ethernet frames
27-28 TxVTagMode Read/Write
25-26 RxVTagMode Read/Write
Transmit VLAN Tag Mode. These bits select the operation mode for
transmit VLAN tagging and are only used when
C_TEMACx_TXVLAN_TAG = 1. The VLAN tag that is added is from the
TTAGx register. Valid VLAN TPID values must be initialized in the TPIDx0
and TPIDx1 registers. For mode 11, the Transmit VLAN data table must be
initialized. Please refer to the VLAN section of this document for more
00 ^details.
00 - No VLAN tags will be added to transmit frames
01 - VLAN tags will be added to all transmit frames
10 - VLAN tags will be added to all transmit frames that already have a
VLAN tag
11 - VLAN tags will be added to select transmit frames that already have
VLAN tags
Receive VLAN Tag Mode. These bits select the operation mode for
receive VLAN tagging and are only used when
C_TEMACx_RXVLAN_TAG = 1. The VLAN tag that is added is from the
RTAGx register. Valid VLAN TPID values must be initialized in the TPIDx0
and TPIDx1 registers. For mode 11, the Receive VLAN data table must be
initialized. Please refer to the VLAN section of this document for more
00 ^details.
00 - No VLAN tags will be added to receive frames
01 - VLAN tags will be added to all receive frames
10 - VLAN tags will be added to all receive frames that already have a
VLAN tag
11 - VLAN tags will be added to select receive frames that already have
VLAN tags
