12 - THE R/G/B OUTPUT PICTURE
The following tables show the picture design in R/G/B output mode, according to :
- Blink on/off (BK character attribute & C[6:4] control bits)
- Character background on/off (BE character attribute & C1 control bit)
- Character border on/off (FBE row attribute)
- C3 = 0 : CSCREEN, CBACKG and CBORD are page attributes, defined by the color register.
- C3 = 1 : CSCREEN is defined by the color register. CBACKG and CBORD are identical to CCHAR and
A R/G/B external switch must be controlled by the STV5730 FB output to perform the character insertion.
C0 may be used as an additional character intensity signal.
