Default 0		Enables 4-bit serial interface when set
03-wire SPI is used with SDIO pin operating as bidirectional I/O port
14-wire SPI is used with SDIO pin operating as data input and SDO pin as data output port.
D14DecFil/ Burst
Default 0		2x decimation filter (Receive Mode) is enabled when bit is set

0Low Pass
1High Pass
D5Burst Rate
Default 0		Low resolution output data rate in burst mode
0Low resolution (9-bit) full output rate
1Decimated low resolution output (4x decimation, 11-bit resolution)
D2Auto Trigger
Default 0		Enables auto trigger mode in burst mode without the need to control the trigger pin.
0Manual trigger mode using the external trigger input pin
1Auto trigger mode enabled

D10-D7Over-range thresholdThe over-range detection is triggered 12 output clock cycles after the overload condition occurs. The threshold at which the OVR is triggered = 1.0V x [decimal value of <Over-range threshold>]/16. After power up or reset, the default value is 15 (decimal) which corresponds to a OVR threshold of 0.56dB below fullscale (20*log(15/16)). This OVR threshold is applicable to both channels.
