Table 9. LED Pulse Stretch Settings (Register 20)

Bit	Name			Description	Type	Default

		00		= Stretch LED events to 30 ms.
20.3:2	LEDFREQ	01		= Stretch LED events to 60 ms.	R/W	00
20.3:2	LEDFREQ	10		= Stretch LED events to 100 ms.	R/W	00
		10		= Stretch LED events to 100 ms.
		11 = Reserved.

20.1	PULSE-	0	= Disable pulse stretching of all LEDs.		R/W	1
20.1	STRETCH	1	= Enable pulse stretching of all LEDs.		R/W	1
	STRETCH	1	= Enable pulse stretching of all LEDs.

5.2Inter Frame Status LEDs

By using the conversion FPGAs, the Inter Frame Status information for Speed status, Duplex status, and Link status are output to an LED circuit. The LEDs (D101 - D154) provide a continuous, real-time status for all eight ports. This feature is provided to assist the customer in evaluation of the Inter Frame Status operation.
