SRDA[1:0]

Sampling mode selection

These bits control the sampling mode of DAC operation. In Auto mode, the sampling mode is

automatically set according to multiples between the system clock and sampling clock: single rate

for 512 fS, 768 fS, and 1152 fS, dual rate for 256 fS or 384 fS, and quad rate for 128 fS and 192 fS.

Default value = 00.

PSMDA

Power-save mode selection

This bit selects the power-save mode for the OPEDA function. When PSMDA = 0, OPEDA

controls the power-save mode and normal operation. When PSMDA = 1, OPEDA functions

controls the DAC disable (not power-save mode) and normal operation.

Default value: 0.

FMTDA[2:0] Audio interface format selection

These bits control the audio interface format for DAC operation. Details of the format and any

related restrictions with the system clock are described in the Audio Data Interface Formats and

Timing section.

Default value: 0000 (16-/20-/24-/32-bit I2S format).
