Description
0: SDIO pin configured for input only during data transfer (4-wire interface).
1: SDIO pin configured for input or output during data transfer (3-wire interface).
0: Serial data uses MSB first format.
1: Serial data uses LSB first format.
1: Initiate a software reset; this bit is set to 0 upon reset completion.
0: Use 1 byte preamble (5 address bits).
1: Use 2 byte preamble (13 address bits).
1: Shuts down DAC output current internal band gap reference.
1: DAC output current off.
1: Disables internal master clock.
0: Internal band gap reference.
1: External reference.

Description
Hardware version identifier.
Description
0: Unsigned binary input data format.
1: Twos complement input data format.
0: Data latched on DATACLK rising edge always.
1: Data latched on DATACLK falling edge (only active in DESKEW mode).
0: DESKEW mode disabled.
1: DESKEW mode enabled (adds a register in digital data path to remove
skew in received data; one clock cycle of latency is introduced).
0: Single-ended clock input.
1: Differential clock input.
0: Calibration clock disabled.
1: Calibration clock enabled.
Calibration clock divide ratio from DAC clock rate.
