WIDTH_CHn ADC Channels output data word width control
1 = 24-bit mode for the corresponding channel
0 = 16-bit mode for the corresponding channel (default)
DR_LTY: Data Ready Latency Control for DRA, DRB, and DRC pins
1 = True “No Latency” Conversion, data ready pulses after 3 DRCLK periods (DEFAULT)
0 = Unsettled Data is available after every DRCLK period
DR_HIZ: Data Ready Pin Inactive State Control for DRA, DRB, and DRC pins
1 = The Default state is a logic high when data is NOT ready
0 = The Default state is high impedance when data is NOT ready (DEFAULT)
DR_LINK Data Ready Link Control
1 = Data Ready Link turned ON, all channels linked and data ready pulses from the most lagging ADC
0 = Data Ready Link tunred OFF (DEFAULT)
DRC_MODE[1:0]
11 = Both Data Ready pulses from CH4 and CH5 are output on DRC pin.
