Table 13-38. PHY Link Health Register Bit Description

Field	Bit(s)	Description	Mode	HW Rst	SW Rst
		Auto-Negotiate Fault: This is the logical
Auto-Negotiation	6	OR of PHY register 1, bit 4, PHY	RO	0b	0b
Fault		register 6, bit 4, and PHY register 10, bit
		15.
Reserved	7	Always read as 0b.	RO	0b	0b
		Mode:
Data Err[0]	8	10: 10 Mbps polarity error.	LH	0b	0b
		100: Symbol error.
		1000: Gig idle error.
		Mode:
Data Err[1]	9	10: Reserved.	RO/	0b	0b
		100: Scrambler unlocked.	LH
		1000: Local receiver not OK.
Count Overflow	10	The idle error counter has overflowed.	RO/	0b	0b
			LH
Gigabit Rem Rcvr		Gig has detected a remote receiver	RO/
	11	status error. This is a latched high		0b	0b
NOK			LH
		version of PHY register 10, bit 12.
		Gig has resolved to master. This is a
Gigabit Master	12	duplicate of PHY register 10, bit 14.	RO	0b	0b
Resolution		Programmers must read PHY register
		10, bit 14 to clear this bit.
		A fault has occurred with the gig master/
		slave resolution process. This is a copy
Gigabit Master Fault	13	of PHY register 10, bit 15.	RO	0b	0b
		Programmers must read PHY register
		10, bit 15 to clear this bit.
		1b indicates that the PHY has detected
		gigabit connection errors that are most
		likely due to a non-IEEE compliant
		scrambler in the link partner.
Gigabit Scrambler	14	0b = Normal scrambled data.	RO	0b	0b
Error		Definition is: If an_enable is true and in
		Gigabit mode, on the rising edge of
		internal signal link_fail_inibit
		timer_done, the dsp_lock is true but
		loc_rcvr_OK is false.
SS Downgrade	15	Smart Speed has downgraded the link	RO/	0b	0b
		speed from the maximum advertised.	LH
