Intel IXF1104 manual MAC Control Registers, Station Address $ PortIndex +0x00 +0x01

Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

8.4.1MAC Control Registers

Table 70 through Table 92 “Port Multicast Address ($ Port_Index +0x1A – +0x1B)” on page 173 provide details on the control and status registers associated with each MAC port. The register address is ‘Port_index + 0x**’, where the port index is set at any value from 0x0 through 0x5. All registers are 32-bit. The unused bits of the registers are read-only and are set permanently to zero.

Table 70. Station Address ($ Port_Index +0x00 – +0x01)

Name	Description	Address	Type1	Default
	Source MAC address bit 31-0.
Station Address	This address is inserted in the source address	Port_Index
	field when transmitting pause frames, and is also		R/W	0x0000000
Low		+ 0x00
	used to compare against unicast pause frames
	at the receiving side.
	Source MAC address bit 47-32.
	This address is inserted in the source address
Station Address	field when transmitting pause frames, and is also	Port_Index	R/W	0x00000000
High	used to compare against unicast pause frames	+ 0x01
	at the receiving side. Bits 15:0 of this register are
	assigned to bits 47:32 of the station address.

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

Table 71. Desired Duplex ($ Port_Index + 0x02)

Bit	Name	Description		Type1	Default
Register Description: Chooses between half-duplex and full-duplex operation in RGMII
100 Mbps or 10 Mbps mode only.					0x00000001
This register must be set to the default value of 1 and must not be changed when operating in
RGMII 1000 Mbps, GMII, or fiber mode.
31:1	Reserved	Reserved		R	0x00000000
		0 =	Half-duplex
		1 =	Full-duplex
0	Duplex Select	NOTE: Half-duplex operation applies only to		R/W	1
		10/100 Mbps speed on copper media in RGMII
		mode only. Gigabit speed on either media requires
		full-duplex.

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

Table 72. FD FC Type ($ Port_Index + 0x03)

Name	Description	Address	Type1	Default
	This value fills the Type field of the Transmitted	Port_Index
FD FC Type	Pause frames. Only bits 15:0 of this register are		R/W	0x00008808
		+ 0x03
	used.

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
