FDAC Register (Reg. 7, Address 000111)
The FDAC register is used to set the Fine Offset DAC in the Manual Calibration mode. See Calibration
Option, in the Black Level Offset Calibration section for more information.
Control Register (Reg. 8, Address 001000)
The Control register is used to set various test and power-down modes.
DIGtest=0, please leave this bit in the default setting.
ADCtest=0, connects PGA output to ADC input.
ADCtest=1, connects ADCinP & ADCinN pins to ADC input.
NoCDS=0, connects CDS output to PGA input.
NoCDS=1, connects Test1 & Test2 pins to PGA inputs (CDS by-pass mode).
Low Power=0, selects the normal, 12 bit ADC mode.
Low Power=1, selects the low power, 6 bit ADC mode.
OE=0, digital outputs in high-Z state.
OE=1, digital outputs enabled.
DAC1pd=1, Utility DAC1 is powered down.
DAC0pd=1, Utility DAC0 is powered down.
AFEpd=1, CDS & PGA are powered down, do not use.
ADCpd=1, ADC is powered down, do not use.
PwrDwn=1, the whole chip is powered down.
Polarity Register (Reg. 9, Address 001001)
The Polarity register is used to set the polarity for the 6 input clock signals.
For each clock: polarity bit=0 sets clock active low, polarity bit=1 sets clock active high.
