Restore Default Register Values. Default values of SPI registers can be restored at the rising edge of this bit.
Sampling Clock Phase. This is for synchronizing sampling edge for multiple devices while the ADC16DV160 is
configured at clock divide by 2.
Clock divider. Internal operating clock frequency can be programmed either to be divided by 1 or 2.
Reserved. Must be set to 0.
Output Clock Phase Adjustment. User can adjust output clock phase from 31° to 143°. Each 1 LSB increment
results in about 16° of output clock phase increase.
