SUMR0
Summation Register 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 Count Interrupt. AI in EICON (SFR D8h) must also be cleared.

ODAC
Offset DAC Register. 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 with the ADC input prior to conversion. Writing 00h or 80h to ODAC turns off the offset DAC.
bit 7
Offset DAC Sign bit.

NOTE: ODAC cannot be used to offset the input so that the buffer can be used for AGND signals. Offset DAC should be
cleared before offset calibration, since the offset DAC output is applied directly to the ADC input.
