PCM Format A signifies the data word beginning one SCLK bit following the
I2S_LRCLK transition, as in I2S Mode. PCM Format B signifies the data word begin-
ning after the I2S_LRCLK transition, as in Left Justified.
In Slave mode, the pulse width of the I2S_LRCLK does not matter. The pulse can
range from one cycle high to all but one cycle high. In Master mode, it will be driven
one cycle high.
Figure 13 shows a functional drawing of the different formats in master mode.
The SGTL5000 contains a digital audio processing block (DAP) attached to the
source select switch. The digitized signal from the source select switch can be
routed into the DAP block for audio processing. The DAP has the following 5 sub
blocks:
