Description

DITHEN

Dither enable is applicable only for 16-bit data width modes.

0 = disabled (default).

1 = enabled.

LRMOD

LRCLK mode sets the LRCLK for either a 50% duty cycle or a pulse. The pulse mode should be at least 1 BCLK wide.

0 = 50% duty cycle (default).

1 = pulse mode.

BPOL

BCLK polarity sets the BCLK edge that triggers a change in audio data. This can be set for the falling or rising edge of the BCLK.

0 = falling edge (default).

1 = rising edge.

LRPOL

LRCLK polarity sets the LRCLK edge that triggers the beginning of the left channel audio frame. This can be set for the falling or rising edge

of the LRCLK.

0 = falling edge (default).

1 = rising edge.

[2:1]

CHPF[1:0]

Channels per frame sets the number of channels per LRCLK frame.

Setting

Channels per LRCLK Frame

Stereo (default)

TDM 4

Reserved

Serial data port bus mode. Both LRCLK and BCLK are main of the serial port when set in main mode and are serial port subordinate in

subordinate mode.

0 = subordinate mode (default).

1 = main mode.
