Memory Maps and Bit Descriptions
Egress FIFO Start of Packet Error Interrupt Mask Per Port: Egress
FIFO Start of Packet Error interrupt mask for the 16 Egress FIFOs (one
per port). A 0 disables the mask. An interrupt will be generated when the
appropriate FIFO/Port receives consecutive End of Packets. The
interrupt is cleared by reading the status register Egress FIFO Start of
Packet Error Status. If this bit is 1, no interrupt will be generated.
Reserved
Egress FIFO PHY/Port Enable Per Port: Egress FIFO/Port Enable bits
for the 16 Egress FIFOs (one per port).
Reserved
Egress FIFO Streaming Threshold Port 0: Egress FIFO Streaming
threshold in bytes for Port 0. 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
Egress FIFO Streaming Threshold Port 1: Egress FIFO Streaming
threshold in bytes for Port 1. 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.
