VALUE
FUNCTION
D7
ADOVF
0
ADC over flow. This bit indicates whether the ADC is overflow.
ADOVF = 0 No overflow.
ADOVF = 1 A/D is overflow.
D6
CX
0
Continuous data transfer mode. This bit selects between programming mode and continuous data transfer
mode.
CX = 0
Programming mode.
CX = 1
Continuous data transfer mode.
D5
IIR
0
IIR Filter. This bit selects between FIR and IIR for decimation/interpolation low-pass filter.
IIR = 0
FIR filter is selected.
IIR = 1
IIR filter is selected.
D4
DAOVF
0
DAC over flow. This bit indicates whether the DAC is overflow
DAOVF = 0 No overflow.
DAOVF = 1 DAC is overflow
D3
BIASV
0
Bias voltage. This bit selects the output voltage for BIAS pin
BIASV = 0
BIAS pin = 2.35V
BIASV = 1
BIAS pin = 1.35V
D2
ALB
0
Analog loop back
DLB = 0
Analog loopback disabled
DLB = 1
Analog loopback enabled
D1
DLB
0
Digital loop back
DLB = 0
Digital loopback disabled
DLB = 1
Digital loopback enabled
D0
DAC16
0
DAC 16-bit data format. This bit applies to the continuous data transfer mode only to enable the 16-bit data
format for DAC input.
DAC16 = 0
DAC input data length is 15 bits. Writing a 1 to the LSB of the DAC input to switch from continuous
data transfer mode to programming mode.
DAC16 = 1
DAC input data length is 16 bit.
