| H A D | dai.rst | 15 The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
27 Rx lines are used for audio transmission, while the bit clock (BCLK) and
29 controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
38 MSB is transmitted on the falling edge of the first BCLK after LRC
51 flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
61 MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
