8 OPA2HCMDIS 0 RW High Common Mode Disable.
Set to disable high common mode. Disables rail-to-rail on input, while output still remains rail-to-rail. The input voltage to the opamp
while HCM is disabled is restricted between VSS and VDD-1.2V.
7 OPA1HCMDIS 0 RW High Common Mode Disable.
Set to disable high common mode. Disables rail-to-rail on input, while output still remains rail-to-rail. The input voltage to the opamp
while HCM is disabled is restricted between VSS and VDD-1.2V.
6 OPA0HCMDIS 0 RW High Common Mode Disable.
Set to disable high common mode. Disables rail-to-rail on input, while output still remains rail-to-rail. The input voltage to the opamp
while HCM is disabled is restricted between VSS and VDD-1.2V.

5:0 OPA2OFFSET 0x00 RW OPA2 Offset Configuration Value
This register contains the offset calibration value for OPA2. This field is set to the production OPA2 offset calibration value, hence
the reset value might differ from device to device. The field is sign-magnitude encoded. Higher values lead to lower OPA results.
The resolution of the LSB is 1.6mV/LSB
