READ<1:0>: Address Loop Setting bits
11 = Address counter loops on entire register map
10 = Address counter loops on register types (default)
01 = Address counter loops on register groups
00 = Address not incremented, continually read same single register
DR_LTY: Data Ready Latency Control bit
1 = “No Latency” Conversion, DR pulses after 3 DRCLK periods (default)
0 = Unsettled Data is available after every DRCLK period
DR_HIZN: Data Ready Pin Inactive State Control bit
1 = The data ready pin default state is a logic high when data is NOT ready
0 = The data ready pin default state is high-impedance when data is NOT ready (default)
DRMODE<1:0>: Data Ready Pin (DR) Control bits
11 = Both Data Ready pulses from ADC0 and ADC Channel 1 are output on the DR pin.
10 = Data Ready pulses from ADC Channel 1 are output on the DR pin. DR from ADC Channel 0 are not
01 = Data Ready pulses from ADC Channel 0 are output on the DR pin. DR from ADC Channel 1 are not
00 = Data Ready pulses from the lagging ADC between the two are output on the DR pin. The lagging
DRSTATUS_CH<1:0>: Data Ready Status bits
11 = ADC Channel 1 and Channel 0 data is not ready (default)
10 = ADC Channel 1 data is not ready, ADC Channel 0 data is ready
01 = ADC Channel 0 data is not ready, ADC Channel 1 data is ready
00 = ADC Channel 1 and Channel 0 data is ready
