Global RX Block Register Overview
Table 71 through Table 75 on page 100 provide an overview of the RX Block Registers, which
include the RX FIFO High and Low watermarks.
Table 71. RX FIFO High Watermark Ports 0 to 9 Registers (Addr: 0x580 - 0x589)

Description
Address
Type1
Default
RX FIFO High
Watermark Port 0
High watermark for RX FIFO port 0. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x580
R/W
0x00000740
RX FIFO High
Watermark Port 1
High watermark for RX FIFO port 1. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x581
R/W
0x00000740
RX FIFO High
Watermark Port 2
High watermark for RX FIFO port 2. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x582
R/W
0x00000740
RX FIFO High
Watermark Port 3
High watermark for RX FIFO port 3. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x583
R/W
0x00000740
RX FIFO High
Watermark Port 4
High watermark for RX FIFO port 4. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x584
R/W
0x00000740
RX FIFO High
Watermark Port 5
High watermark for RX FIFO port 5. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x585
R/W
0x00000740
RX FIFO High
Watermark Port 6
High watermark for RX FIFO port 6. The default
value is 1856 bytes. When the amount of data
stored in the FIFO exceeds this value, a flow
control command is sent to the corresponding TX
MAC.
0x586
R/W
0x00000740
1. RO = Read Only; RR = Clear on Read; W = Write; R/W = Read/Write
2. For all RX FIFO High Watermark Registers, the following bit definitions apply to all ports (0:9):
Bits 31:15 - Reserved and RO.
Bits 14:0 - Described above.
