FUNCTION
TDM Mode Select
0 = LRCLK signal polarity indicates left and right audio.
1 = LRCLK is a framing pulse that transitions polarity to indicate the start of a frame of audio data consisting
TDM
of multiple channels.
When operating in TDM mode, the left channel is output immediately following the frame sync pulse. If right-
channel data is being transmitted, the 2nd channel of data immediately follows the 1st channel data.
Mono Playback Mode
DMONO
0 = Stereo data input on SDIN is processed separately.
1 = Stereo data input on SDIN is mixed to a single channel and routed to both the left and right DAC.
BCLK Select
Configures BCLK when operating in master mode. BSEL has no effect in slave mode. Set BSEL = 010, unless
sharing the bus with multiple devices:
000 = Off
001 = 64x LRCLK (192x internal clock divided by 3)
BSEL
010 = 48x LRCLK (192x internal clock divided by 4)
011 = Reserved for future use.
100 = PCLK/2
101 = PCLK/4
110 = PCLK/8
111 = PCLK/16
