Intel IXF1104 manual TX Config Word $ PortIndex + 0x17 Sheet 2

IXF1104 4-Port Gigabit Ethernet Media Access Controller

Table 89. TX Config Word ($ Port_Index + 0x17) (Sheet 2 of 2)

Bit	Name	Description		Type1	Default
		Remote fault definitions:
		00	= No error, link okay
13:122	Remote Fault [1:0]	01	= Offline	R/W	00
		10	= Link failure
		11 = Auto-negotiation_Error
11:9	Reserved	Write as 0, ignore on Read		R/W	000
8	Asym Pause	Asym Pause. The ability to send pause frames.		R/W	1
7	Sym Pause	Sym Pause. The ability to send and receive pause		R/W	1
		frames.
6	Half Duplex	Half-duplex		R/W	1
5	Full Duplex	Full-duplex		R/W	1
4:0	Reserved	Write as 0, ignore on read		R/W	0x00

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

NOTE: A value of 0x0 must be written to all reserved bits of the “TX Config Word ($ Port_Index + 0x17)” Register.

Table 90. Diverse Config Write ($ Port_Index + 0x18) (Sheet 1 of 2)

Bit	Name	Description	Type1	Default
Register Description: This register contains various configuration bits for general use.				0x00110D
31:19	Reserved	Reserved	RO	0x0000
18:13	Reserved	Write as 0, ignore on Read.	R/W	0x0000
12	Reserved2	Write as 1, ignore on Read.	R/W	1
11-9	Reserved2	Write as 0, ignore on Read.	R/W	0x0
8	Reserved2	Write as 1, ignore on Read.	R/W	1
		0 = Normal operation
		1 = Enable padding of undersized packets
7	pad_enable	NOTE: Assertion of this bit results in the	R/W	0
		automatic addition of a CRC to the
		padded packet.
6	crc_add	0 = Normal operation	R/W	0
		1 = Enable automatic CRC appending
		Enable auto-negotiation (used for fiber mode only)
		to be performed by the hardware state machines
		in the MAC.
5	AN_enable	The hardware auto-negotiation (AN) state	R/W	0
		machine controls the config words transmitted
		when this bit is set.
		NOTE: In copper mode, this bit must be set to 0
		(reserved).
42	Reserved	Write as 0, ignore on Read.	R/W	0

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

2. Reserved bits must be written to the default value for proper operation.
