NAME
DESCRIPTION
DAI1/DAI2 Master Mode
In master mode, DAI1/DAI2 outputs LRCLK and BCLK. In slave mode, DAI1/DAI2
accept LRCLK and BCLK as inputs.
0 = Slave mode
1 = Master mode
DAI1/DAI2 Word Clock Invert
TDM1/TDM2 = 0:
0 = Left-channel data is transmitted while LRCLK is low.
1 = Right-channel data is transmitted while LRCLK is low.
TDM1/TDM2 = 1:
Always set WCI = 0.
DAI1/DAI2 Bit Clock Invert
BCI1/BCI2 must be set to 1 when TDM1/TDM2 = 1.
0 = SDIN is accepted on the rising edge of BCLK.
1 = SDIN is accepted on the falling edge of BCLK.
Master Mode:
0 = LRCLK transitions on the falling edge of BCLK.
1 = LRCLK transitions on the rising edge of BCLK.
DAI1/DAI2 Data Delay
DLY1/DLY2 has no effect when TDM1/TDM2 = 1.
0 = The most significant data bit is clocked on the first active BCLK edge after an
1 = The most significant data bit is clocked on the second active BCLK edge after an
DAI1/DAI2 Time-Division Multiplex Mode (TDM Mode)
Set TDM1/TDM2 when communicating with devices that use a frame synchronization
pulse on LRCLK instead of a square wave.
0 = Disabled
1 = Enabled (BCI1/BCI2 must be set to 1)
DAI1/DAI2 Wide Frame Sync Pulse
Increases the width of the frame sync pulse to the full data width when TDM1/TDM2 =
1. FSW1/FSW2 has no effect when TDM1/TDM2 = 0.
0 = Disabled
1 = Enabled
DAI1/DAI2 Audio Data Bit Depth
Determines the maximum bit depth of audio being transmitted and received. Data is
always 16 bit when TDM1/TMD2 = 0.
0 = 16 bits
1 = 24 bits
SDOUT is valid on the rising edge of BCLK.
SDOUT is valid on the falling edge of BCLK.
