■ Audio Interface Format
Data is shifted in via the SDTI pin using BICK and LRCK inputs. The DIF1-0 bits as shown in Table 2 can select four
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 3 can be used for 16bit I2S Compatible format by zeroing the unused LSBs at BICK
≥ 48fs or BICK = 32fs.
