Atlas 520099 Dimming for Output a front headlight, Rear marker lights, Dimming of Rear Headlight

Decoder for Atlas N Scale H15/16-44 Locomotives					11
CV	Description			Range	Default
					Value**
51	Notes for CV51:
	Bits 4 to 7 of CV51 are effective if and only if CV51.0=1.
	Dimming is inactive if any of bits 4 to 7 are set to “1.”
	If more than one of Bits 4 to 7 of CV51 is set to “1,” only the highest
	numbered of these bits is effective.
52	Dimming for Output A (front headlight)			0-255	64
	The value in CV52 is used to dim the front headlight.
	Using the value “0” for this CV results in a completely
	dark front headlight, when it is dimmed.
	Using the value “255” keeps the front headlight at its
	maximum possible brightness, even when dimmed.
54	Function Mapping for Outputs C and D (front and			0-255	2

	Bit 1	0	= No effect	0,1	1
		1	= Marker lights controlled by F2		(2)
	Bit 2	0	= No effect	0,1	0
		1	= Marker lights controlled by F3		(4)
	Bit 3	0	= No effect	0,1	0
		1	= Marker lights controlled by F4		(8)
	Bit 4	0	= No effect	0,1	0
		1	= Marker lights controlled by F5		(16)
	Bit 5	0	= No effect	0,1	0
		1	= Marker lights controlled by F6		(32)
	Bit 6	0	= No effect	0,1	0
		1	= Marker lights controlled by F7		(64)
	Bit 7	0	= No effect	0,1	0
		1	= Marker lights controlled by F8		(128)
57	Lighting Effects for Output B (rear headlight)			0-246	6
	Bit 0	Not used			0
	Bit 1	Rear Headlight Dimming Control:		0,1	1
		If CV57.2=1, the value in CV58 is used for			(2)
		front headlight dimming with the dimming
		controlled as follows:
		CV57.1=0: Rear headlight always dimmed
		CV57.1=1: If CV51.0=0, function F1 dims
		rear headlight; if CV51.0=1, function F4 dims
		rear headlight.
	Bit 2	Dimming of Rear Headlight:		0,1	1
		0	= Rear headlight cannot be dimmed		(4)
		1	= Rear headlight can be dimmed
