- Memory Maps and Bit Descriptions -
Egress FIFO Streaming Threshold Port 31: Egress FIFO Streaming
threshold in bytes for Port 31. The values are:
000 - 64 Bytes
001 - 128 Bytes
010 - 256 Bytes
011 - 512 Bytes
100 - 768 Bytes
101 - 1544 Bytes
110 & 111 - Reserved
When the Port is in Streaming mode and the Egress FIFO reaches the
programmed threshold, an indication is sent to the associated
Configurable MAC block to transfer the Port’s Packet Data across the
Ethernet interface.
Reserved
Ingress FIFO Packet Drop Counter Port 0: The Ingress FIFO Packet
Drop Counter counts dropped packets due to the MAC detecting an
error. Packets are dropped in store and forward mode only (Ingress
FIFO Mode = 0). Clear on Read.
Ingress FIFO Packet Drop Counter Port 1: The Ingress FIFO Packet
Drop Counter counts dropped packets due to the MAC detecting an
error. Packets are dropped in store and forward mode only (Ingress
FIFO Mode = 0). Clear on Read.
Ingress FIFO Packet Drop Counter Port 31: The Ingress FIFO Packet
Drop Counter counts dropped packets due to the MAC detecting an
error. Packets are dropped in store and forward mode only (Ingress
FIFO Mode = 0). Clear on Read.
Ingress FIFO Full Interrupt Status Per Port: FIFO full Status for the 32
Ingress FIFOs (one per port).
Ingress FIFO Near Full Interrupt Status: FIFO Near full Status for the
32 Ingress FIFOs (one per port). A Port will go into a near full condition
when its Ingress FIFO level goes beyond the Pause Frame High
Threshold value associated with that port.
