Table 82. MAC IF Mode and RGMII Speed ($ Port_Index + 0x10)

Bit	Name	Description			Type1	Default
Register Description – MAC IF Mode: Determines the MAC operation frequency and mode
per port.
Changes to the data setting of this register must be made in conjunction with the				“Clock and		0x00000003
Interface Mode Change Enable Ports 0 - 3 ($0x794)" to ensure a safe transition to a new
operational mode. Changes to this register must follow a proper sequence. Refer to Section
6.1, “Change Port Mode Initialization Sequence” on page 129 for the proper sequence for
changing the port mode and speed.
31:3	Reserved	Reserved			R	0x00000000
		These bits are used to define the clock mode and
		the RGMII/GMII mode of operation.
		000	= Reserved
		001	= Reserved
2:0	Port Mode	010 = GMII 1000 Mbps operation			R/W	011
		011 = Reserved
		100	= RGMII 10 Mbps operation
		101	= RGMII 100 Mbps operation
		11x = RGMII 1000 Mbps operation

Table 83. Flush TX ($ Port_Index + 0x11)

Bit	Name	Description	Type1	Default
Register Description: Used to flush all TX data. It is used if all traffic sent to a port should be				0x00000000
stopped.
31:1	Reserved	Reserved	R	0x00000000
0	Flush TX	This bit flushes all TX data and is used if all the	R/W	0
		traffic sent to a port should be stopped.

1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No clear; R/W/C = Read/Write, Clear on Write
