Channel A Input Data Bit 9 (MSB)/Power-Down Control Bit:
0: Enter DAC standby mode (DACEN = 0) or power up DAC (DACEN = 1).
1: Enter power-down mode.
Channel A Input Data Bit 8/DAC Enable Control Bit:
0: Enter DAC standby mode with PD = 0.
1: Power up DAC with PD = 0.
X: Enter power-down mode with PD = 1 (X = don’t care).
Channel A Input Data Bit 7/Second Interpolation Filter Enable Bit:
0: Interpolation mode is determined by F1EN.
Enable 4x interpolation mode. (F1EN must equal 1.)
Channel A Input Data Bit 6/First Interpolation Filter Enable Bit:
0: Interpolation disable.
1: Enable 2x interpolation.
