Bit Clock Directional Control
0: BCLK_x (or GPIO2_x if programmed as BCLK_x) is an input (slave mode).
1: BCLK_x (or GPIO2_x if programmed as BCLK_x) is an output (master mode).
Word Clock Directional Control
0: WCLK_x (or GPIO1_x if programmed as WCLK_x) is an input (slave mode).
1: WCLK_x (or GPIO1_x if programmed as WCLK_x) is an output (master mode).
Serial Output Data Driver (DOUT_x) 3-State Control
0: Do not place DOUT_x in high-impedance state when valid data is not being sent.
1: Place DOUT_x in high-impedance state when valid data is not being sent.
Bit/ Word Clock Drive Control
0:
BCLK_x (or GPIO2_x if programmed as BCLK_x) / WCLK_x (or GPIO1_x if programmed as
WCLK_x) does not continue to be transmitted when running in master mode if codec is powered
down.
1:
BCLK_x (or GPIO2_x if programmed as BCLK_x) / WCLK_x (or GPIO1_x if programmed as
WCLK_x) continues to be transmitted when running in master mode, even if codec is powered down.
Reserved. Do not write to this register bit.
3-D Effect Control
0: Disable 3-D digital effect processing.
1: Enable 3-D digital effect processing.
Digital Microphone Functionality Control
00: Digital microphone support is disabled.
01: Digital microphone support is enabled with an oversampling rate of 128.
10: Digital microphone support is enabled with an oversampling rate of 64.
11: Digital microphone support is enabled with an oversampling rate of 32.

Audio Serial Data Interface Transfer Mode
00: Serial data bus uses I

S mode.
01: Serial data bus uses DSP mode.
10: Serial data bus uses right-justified mode.
11: Serial data bus uses left-justified mode.
Audio Serial Data Word Length Control
00: Audio data word length = 16 bits
01: Audio data word length = 20 bits
10: Audio data word length = 24 bits
11: Audio data word length = 32 bits
Bit Clock Rate Control
This register only has effect when bit clock is programmed as an output.
0: Continuous-transfer mode used to determine master-mode bit clock rate
1: 256-clock transfer mode used, resulting in 256 bit clocks per frame
DAC Re-Sync
0: Don’t care
1: Re-sync stereo DAC with codec interface if the group delay changes by more than ±DAC (f
S
/4).
ADC Re-Sync
0: Don’t care
1: Re-sync stereo ADC with codec interface if the group delay changes by more than ±ADC (f
S
/4).
Re-Sync Mute Behavior
0: Re-sync is done without soft-muting the channel. (ADC/DAC)
1: Re-sync is done by internally soft-muting the channel. (ADC/DAC)
