n Audio Serial Interface Format
Audio data is input to the AK4356 via the SDTI1-3 pins using BICK and LRCK inputs. 5 serial data formats are supported
and selected by DIF2-0 pins or DIF2-0 bits (See Table 3, compatible with the AK4324/4393). 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 20 and 16 MSB
justified formats by zeroing the unused LSBs.
