HP L 5 manual Common 6-Byte Header, Byte 15 MSB LSB Color space Ubyte Pixel encoding mode

Common 6-Byte Header

The short and long forms of the CID command use a common 6-byte header, regardless of which color space is specified. The header data fields, whose meaning may vary according to the color spaces, are present in all color space specifications. The short form and long form of the CID command are explained separately in the following pages.

Byte	15 (MSB)	8	7	0 (LSB)	Byte
0	Color space (UBYTE)		Pixel encoding mode		1
			(UBYTE)
2	Bits/index		Bits/primary #1		3
	(UBYTE)		(UBYTE)
4	Bits/primary #2		Bits/primary #3		5
	(UBYTE)		(UBYTE)

Byte 0 (Color Space)

This byte specifies the color space. The range of values is 0 through 4. All other values are ignored.
