Table 133. Port IP Discovery Timer in 4x mode (SP_IP_DISCOVERY_TIMER) Field Descriptions

Bit	Field	Value	Description
31-28 DISCOVERY_TI			Discovery Timer in 4x mode. The discovery-timer allows time for the link partner to enter its
	MER		DISCOVERY state and if the link partner is supporting 4x mode, for all 4 lanes to be aligned.
		0000b	102.4pS, for debug only
		0001b	0.84ms
		0010b	0.84ms * 2 = 1.68ms
		...
		1001b	0.84ms * 9= 7.56ms (default)
		...
		1111b	0.84ms *15= 12.6ms
27-24	Reserved		Reserved
23-20	PW_TIMER		Port-Write Timer. The timer defines a period to repeat sending an error reporting Port-Write request
			for software assistance. The timer is stopped by software writing to the error detect registers.
		0000b	Disabled. Port-Write is sent once only.
		0001b	107ms-214ms
