[1] PCM Mode
Data is shifted in via the SDATA pin using BICK and LRCK inputs. Five data formats are supported and selected by the
DIF2-0 pins (Parallel mode) or DIF2-0 bits (Serial mode) as shown in Table 11. In all formats 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.
