• SBLK: Soft blanking switch (1: on, 0: off)
• CPS: Clamping input polarity selection (1: pos., 0: neg.)
• NSS: No Signal Switch (1: on., 0: off.)
If this bit is set to ‘1’, this bit blanks the video signal except OSD signal
• HT: Video & OSD half tone (1: on, 0: off)
• CS1/2: Extended cut-off brightness offset current control data bits (CS1 = 90uA/CS2 = 170uA)
• IS2/IS1: OSD intensity mode switch
