TX Block Register Overview
Table 76 through Table 81 on page 109 provide an overview of the TX Block Registers, which
include the TX FIFO High and Low watermark.
Table 76. TX FIFO High Watermark Ports 0 to 9 (Addr: 0x600 - 0x609)

Description
Address
Type1
Default
TX FIFO High
Watermark Port 0
High watermark for TX FIFO port 0. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x600
R/W
0x00000630
TX FIFO High
Watermark Port 1
High watermark for TX FIFO port 1. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x601
R/W
0x00000630
TX FIFO High
Watermark Port 2
High watermark for TX FIFO port 2. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x602
R/W
0x00000630
TX FIFO High
Watermark Port 3
High watermark for TX FIFO port 3. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x603
R/W
0x00000630
TX FIFO High
Watermark Port 4
High watermark for TX FIFO port 4. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x604
R/W
0x00000630
TX FIFO High
Watermark Port 5
High watermark for TX FIFO port 5. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x605
R/W
0x00000630
TX FIFO High
Watermark Port 6
High watermark for TX FIFO port 6. The default
value is 1584 bytes. When the amount of data
stored in the FIFO exceeds this value, the TX
FIFO indicates “SATISFIED.” This implies
further up in the system that no more data must
be sent to this port.
0x606

0x00000630
1. RO = Read Only; RR = Clear on Read; W = Write; R/W = Read/Write
2. For all TX FIFO High Watermark Registers, the following bit definitions apply to all ports (0:9):
Bits 31:13 - Reserved and RO.
Bits 12:0 - Described above.
