In operation disable mode, the DAC output is cut off from DIN and the internal DAC data are reset. If PSMDA = 1, the DAC output is forced into VCOM. If PSMDA = 0, the DAC output is forced into AGND and the DAC goes into a power-down state. For normal operating mode, these bits must be '0'. The serial mode control is effective during operation disable mode. Default value: 0000.
