READ: Address Loop Setting
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
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
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
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
01 = Data Ready pulses from ADC Channel 0 are output on the DR pin. DR from ADC Channel 1 are
00 = Data Ready pulses from the lagging ADC between the two are output on the DR pin. The lagging
DRSTATUS<1:0>: Data Ready Status
11 = ADC Channel 1 and Channel 0 data not ready (Default)
10 = ADC Channel 1 data not ready, ADC Channel 0 data ready
01 = ADC Channel 0 data not ready, ADC Channel 1 data ready
00 = ADC Channel 1 and Channel 0 data ready
