INTR: INT pin reset
0: Normal operation (default)
1: Reset. Error Monitor Registers(07-0BH) are initialized.
STD1-4: ADC1-4 Mode setting
0: Differential mode(Default)
1: Single-ended mode.
When STD* bit =”1”, Single-ended IN*P pin, IN*N pin must be connected to signal common.

0:ADC* HPF off
1:ADC* HPF on (default)
GAIN4-1: ADC1-4 Differential input Voltage setting
0: 1.68Vrms (default)
1: 0.56Vrms.
When GAIN*bit = “1”, input voltage is amplified threefold (+9.5dB)
In order to adjust full scale range to that of the default condition,
attenuation level of each channel should be set at -9.5dB by the ATT7-0 bits (Table 7).
