Audio Serial Interface Format
Data is shifted in via the SDTI pin using BICK and LRCK inputs. The DIF0-2 as shown in Table 7 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.
