ASAHI KASEI
n Audio Serial Interface Format
Data is shifted in via the SDTI pin using BICK and LRCK inputs. 6 serial data modes are supported and selected by
register data of DIF2-0 as shown in Table 4. In all modes the serial data is MSB-first, 2’s compliment format and is
latched on the rising edge of BICK. Mode 4 can be used for 20, 18 and 16 MSB justified formats by zeroing the unused
LSBs.
