NOTES:
1. Parameters calculated from the best-fit curve from 0x0A to 0xFFF. The best-fit curve method is used to deliver coefficients “a” and
“b” of the first order equation: y = a + b*x. VDAC12_xOUT = EO + (1 + EG) * (VREF,DAC12/4095) * DAC12_xDAT, DAC12IR = 1.
2. The offset calibration works on the output operational amplifier. Offset Calibration is triggered setting bit DAC12CALON
3. The offset calibration can be done if DAC12AMPx = {2, 3, 4, 5, 6, 7}. The output operational amplifier is switched off with
DAC12AMPx ={0, 1}. It is recommended that the DAC12 module be configured prior to initiating calibration. Port activity during
calibration may effect accuracy and is not recommended.
