RX FIFO Low
Watermark Port 5
Low watermark for RX FIFO port 5. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

RX FIFO Low
Watermark Port 6
Low watermark for RX FIFO port 6. The default
value is 1840 bytes. When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

Watermark Port 7
Low watermark for RX FIFO port 7. The default
value is 1840 bytes.When the port is in flow
control and the amount of data stored in the FIFO
goes below this value, the flow control command
is terminated in the corresponding TX MAC.

Watermark Port 8
Low watermark for RX FIFO port 8. The default
value is 1840 bytes. When the port is in flow

goes below this value, the flow control command
is terminated in the corresponding TX MAC.

1. RO = Read Only; RR = Clear on Read; W = Write; R/W = Read/Write.
2. For all Number of Frames Removed Registers, the following bit definitions apply to all ports (0:9):
Bits 31:22 - Reserved and RO.
Bits 21:0 - Described above.
