These encoded bits control loopback operations for MAC loopback ENDEC loopback and Transceiver lookback For proper
loopback operation the CAM Address registers and Receive Control register must be initialized to accept the Destination
address of the loopback packet (see Section 3 8)
LB1 LB0
MC MULTICAST PACKET RECEIVED
This bit is set when a packet is received with a Multicast Address
BC BROADCAST PACKET RECEIVED
This bit is set when a packet is received with a Broadcast Address
LPKT LAST PACKET IN RBA
This bit is set when the last packet is buffered into a Receive Buffer Area (RBA) The SONIC-T detects this condition when its
Remaining Buffer Word Count (RBWC0 1) register is less than or equal to the End Of Buffer Count (EOBC) register (See
Section 5 4 2 )
CRS CARRIER SENSE ACTIVITY
Set when CRS is active Indicates the presence of network activity
COL COLLISION ACTIVITY
Indicates that the packet received had a collision occur during reception
CRCR CRC ERROR
Indicates the packet contains a CRC error If the packet also contains a Frame Alignment error FAER will be set instead (see
below)
FAER FRAME ALIGNMENT ERROR
Indicates that the incoming packet was not correctly framed on an 8-bit boundary Note if no CRC errors have occurred this bit
is not set (i e this bit is only set when both a frame alignment and CRC errors occur)
LBK LOOPBACK PACKET RECEIVED
Indicates that the SONIC-T has successfully received a loopback packet
PRX PACKET RECEIVED OK
Indicates that a packet has been received without CRC frame alignment length (run packet) errors or collisions
