: 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 ).

= 1, display of the characters.

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.

12.1.3 - 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.
