Audio Serial Interface Format
The SDTI, SDTO, BCLK and LRCK pins are connected to an external controller. The audio data format has four modes,
MSB-first and 2’s compliment. The data format is set by the DIF1-0 bits. SDTI is latched by “
” of BCLK. SDTO is
latched by “
”.
When DIF1= “0” and DIF0=”1”, only BCLK=64fs is acceptable.
No.
