R/W
dai_clk_en
DAI Master mode control
0 = Slave mode (BCLK/WCLK inputs)
1 = Master mode (BCLK/WCLK outputs)
4
R/W
dai_wclk_tri_state
WLCK tri-state control
0 = WCLK state is set by dai_clk_en. WCLK is set
as output in master mode, and as input in slave
mode
1 = WCLK forced as an input
3
R/W
dai_wclk_pol
DAI word clock polarity control
2
R/W
dai_clk_pol
0 = Normal polarity
1 = Inverted polarity
DAI bit clock polarity control
0 = Normal polarity
1 = Inverted polarity
1:0
R/W
dai_bclks_per_wclk Number of BCLKs per WCLK period when in DAI
Master mode
00 = 32 BCLKS per WCLK
01 = 64 BCLKS per WCLK
10 = 128 BCLKS per WCLK
11 = 256 BCLKS per WCLK
