Bits 18:0 – NEG[18:0]

The accumulated result of the negative-side measurements. The controller supports up to 128x oversampling; therefore, each polarity can accumulate up to 18 bits when using 12-bit ADC (actual number of bits = ADCBITS + 7). The accumulation is not shifted back down to create an average. Therefore, if oversampling was requested, the software will need to account for the left-shift of the result returned.
