ASAHI KASEI
n 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.
