n Audio Serial Interface Format
Data is shifted in via these SDTI1, SDTI2,and SDTI3 pins using BICK and LRCK inputs.The DIF0-2 as shown in Table7 can
select five serial data modes . In all modes the serial data is MSB-first,2 ’s compliment format and is latched on the rising edge
of BICK. Mode 2 can be used for 16/20 MSB justified formats by zeroing the unused LSBs.
