The user must configure these bits to turn on DAC and DAC GAIN:
- Set the SD bit in ALPWR register to 0.
- Set the ADC_EN_VREF bit in the ALPWR register to 1.
- Set the DAC_ENABLE bit in the DAC_CTRL_STATUS register to 1.
- Set the 4_20_MA_EN bit in the OP_STAGE_CTRL register for the voltage-output or current-output mode.
- Set the DACCAP_EN bit in the OP_STAGE_CTRL register to connect or disconnect the external capacitor at the DAC output.
- Set the DAC_RATIOMETRIC bit in the DAC_CONFIG register for ratiometric or absolute-voltage output mode.
- Set the TEST_MUX_DAC_EN bit in the AMUX_CTRL register to 1.
