: LINE or CHARACTER spacing:
= 0, spacing descriptor defined as character height (SL[7:0] = 1 to 255 character).
= 1, spacing descriptor defined as scan line height (SL[7:0] = 1 to 255 scan lines).
: Number of selected height (character or scan lines according L/ C ).

CLU[3:0] : Active color selection at the begining of the strip.
C[9:1] : Address of the first character code of the strip.
C0
: Address 0 must be 0.
8.1.3 - Code Format
There are basically 3 kinds of code:
- the control codes from 0 to 15 (00H to 0FH),
- the ROM monochrome character codes from 16 to 255 (10H to FFH),
- the two bytes multicolor character codes from 08F0 to 08FF (Hex).
For code definitions see Table 1.

Single byte codes 00 to 0f are command codes. Single byte codes 10 to ff are monochrome character codes.
Double byte codes 08F0 to 08FF are multicolor character codes.
