1. The above applies when the DA0 register is set to 2Ah.
2. D/A1 has the same circuitry as the avove.
3. When the D/A converter is not used, set the DAiE bit (i = 0,1) in the DACON register to 0 (output disabled) and
4. VREF remains connected even if the VCUT bit in the AD0CON1 register is set to 0 (VREF not connected).
