Description
0: Twos complement data format
1: Unsigned binary input data format
0: I and Q input data onto Port 1 and Port 2, respectively
1: I and Q input data interleaved onto Port 1
0: DATACLK pin, 12 mA drive strength
1: DATACLK pin, 24 mA drive strength
0: Input data latched on DATACLK/DACCLK rising edge (dependent on mode)
