Determines the output data format
Digitally inverts the polarity of output data
Output disable. This works with the OEB pin to control the output pins.
Reduces the ADC reference range 2*(V
max/min input voltages.
Sets the output range of the RLCDAC
Controls the latency from sample to data appearing on output pins
Controls RLCDAC driving VRLC/VBIAS pin to define ended signal
reference voltage or reset level clamp voltage.
When WS=0 these register bit have no effect.
CDS mode timing adjust.
When 1CH=0 these register bits have no effect.
Monochrome mode channel select.
Write this register will causes all function to be reset.
It is recommended that a software reset be performed after a power
on before any other register writes.
Write this register will causes the auto-cycle counter to reset to VINR.
This function is only required when LNBYLN=1.
X0= 8 bits multiplexed (8+8 bits)
01= 8 bits parallel (8-MSB only)
11= 4-bit multiplexed mode (4+4+4+4 bits). This mode is only valid
0= Digital outputs enabled
1= Digital outputs high impedence
0= ADC reference range=2V
1= ADC reference range=1.2V
0= RLCDAC ranges from 0 to AVDD
1= RLCDAC ranges from 0 to V
00= Advance reference sample by 1 ADCK period
01= Default reference sample position
10= Delay reference sample by 1 ADCK period
11= Delay reference sample by 2 ADCK period
00= Select red channel
01= Select green channel
10= Select blue channel
11= Reserved
