Data is shifted in via the SDATA pin using BICK and LRCK inputs. Five data formats are supported and selected by the
DIF0-2 as shown in Table 8. 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.
