SUMR0
Summation 0. This is the least significant byte of the 32-bit summation register, or bits 0 to 7.
bits 70
Write: Will cause values in SUMR30 to be added to the summation register.
Read: Will clear the Summation Interrupt.

ODAC
Offset DAC. This register will shift the input by up to half of the ADC full-scale input range. The Offset DAC
bits 70
value is summed into the ADC prior to conversion. Writing 00h or 80h to ODAC turns off the Offset DAC. The offset
DAC should be cleared prior to calibration, since the offset DAC analog output is applied directly to the ADC input.

Offset DAC Sign Bit.

NOTE: ODAC cannot be used to offset the analog inputs so that the buffer can be used for signals within 50mV of AGND.
