3) Description of registers (Numbers inside parentheses ( ) indicate the number of bits.)
CONTRAST (8)
: Adjusts the R, G and B-OUT (Pins 25, 22 and 18) output amplitude gain
commonly for all three channels.
SUB CONTRAST (8)
: Adjusts the R, G and B-OUT (Pins 25, 22 and 18) output amplitude gain
independently for each channel.
OSD GAIN (4)
: Adjusts the OSD R, G and B (Pins 12, 13 and 14) OSD interval output signal
gain commonly for all three channels.
BRTMODE (2)
: This register changes the output dynamic range.
The 2H setting is recommended.
0H : Output dynamic range 0.5 V to 4.5 V
1H : Output dynamic range 0.5 V to 5.5 V
2H : Output dynamic range 1.0 V to 6.5 V (recommended)
3H : Output dynamic range 2.0 V to 7.5 V
BRIGHTNESS (8)
: Controls the output black level potential.
(Three-channel independent and common control can be selected by BRTSW.
During three-channel common mode, control is performed by the G channel.)
CUT OFF (8)
: This is a general-purpose DAC. Use as a cut-off control is recommended.
BLK MODE (1)
: Switches the blanking level mode
0H : BLK LEVEL=fixed
1H : BLK LEVEL=variable
BLANKING LEVEL (6) : Sets the blanking level when BLK MODE is set to 1H.
BRTSW (1)
: Switches the brightness control between three-channel independent and
three-channel common control. When using three-channel common mode, the
BRIGHTNESS G channel is valid.
0H : Three-channel independent mode
1H : Three-channel common mode
SYNC POL (1)
: Switches the sync separator output polarity during sync-on-green input.
0H : Positive polarity
1H : Negative polarity
VDET MODE (1)
: Switches the video signal detection mode.
0H : B channel only is detected
1H : Signal obtained by adding R, G and B signals is detected
POWER SAVE (1)
: Power save mode selector switch.
0H : Power save not performed
1H : Power save performed
