1 - Enabled
Function:
When enabled, these bits will invert the signal polarity of their respective channels.
Default = 00h
Function:
The level of AIN1 - AIN6 can be adjusted in 0.5 dB increments as dictated by the ADC Soft and Zero Cross
bits (ADC_SZC[1:0]) from +24 to -64 dB. Levels are decoded in two’s complement, as shown in
