In operation disable mode, the DAC output is cut off from DIN with a fade-out sequence, and the internal DAC data is reset. DAC output is forced into VCOMDA if PSMDA = 1, or DAC output is forced into AGNDDA and goes into a power-down state if PSMDA = 0. For normal operating mode, a fade-in sequence is applied on the DAC output in resume process. The serial mode control is effective during operation disable mode. A wait time greater than tDACDLY2 is required for the status change because of power-save control turning on/off. Default value: 0000.
