Audio Serial Interface Format
Data is shifted in/out the SDTI/SDTO pins using BCLK and LRCK inputs. Four serial data are selected by the DIF0
and DIF1 pins as shown in Table 1 . In all modes, the serial data is MSB-first, 2's compliment format and it is latched
by "
" of BCLK.
When DIF1="0" and DIF0="1", only BCLK=64fs is acceptable.
