STA308

map full-scale digital input to full DDX modulation output.

By setting this bit to one deemphasis will implemented on all channels. When this is used it takes the place of

biquad #1 in each channel and any coefficients using biquad #1 will be ignored. DSPB(DSP Bypass) bit must

be set to 0 for Deemphasis to function.

The STA308 features a configurable digital serial audio interface. The settings of the SAIx bits determine how

the output to this interface is interpreted. Six formats are accepted.
