Pre-Amplifier Interface Registers
Blue Channel Gain:
BGAINCTRL (0x8430)
Res’d
Blue Gain
X
BG[6:0]
Bits 6–0
This register determines the gain of the blue video channel. This affects only the blue channel
whereas the contrast register (0x8433) affects all channels.
Bit 7
Reserved and should be set to zero.
Green Channel Gain:
GGAINCTRL (0x8431)
Res’d
Green Gain
X
GG[6:0]
Bits 6–0
This register determines the gain of the green video channel. This affects only the green channel
whereas the contrast register (0x8433) affects all channels.
Bit 7
Reserved and should be set to zero.
Red Channel Gain:
RGAINCTRL (0x8432)
Res’d
Red Gain
X
RG[6:0]
Bits 6–0
This register determines the gain of the red video channel. This affects only the red channel
whereas the contrast register (0x8433) affects all channels.
Bit 7
Reserved and should be set to zero.
Contrast Control:
CONTRCTRL (0x8433)
Res’d
Contrast
X
CG[6:0]
Bits 6–0
This register determines the contrast gain and affects all channels, blue, red and green.
Bit 7
Reserved and should be set to zero.
DAC 1 Output Level:
DAC1CTRL (0x8434)
DAC 1 Output Level
BC[7:0]
Bits 7–0
This register determines the output of DAC 1. The full-scale output is determined by bit 5 of the
DAC Config, OSD Contrast & DC Offset Register.
DAC 2 Output Level:
DAC2CTRL (0x8435)
DAC 2 Output Level
GC[7:0]
Bits 7–0
This register determines the output of DAC 2. The full-scale output is determined by bit 5 of the
DAC Config, OSD Contrast & DC Offset Register.
DAC 3 Output Level:
DAC3CTRL (0x8436)
DAC 3 Output Level
RC[7:0]
