[AK4319A]
Data is shifted in via the SDATA pin using BICK and LRCK inputs. Four serial data modes can be
selected by the DIF0 and DIF1 pins as shown in Table 2 . 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 MSB justified
formats by zeroing the unused LSBs.
