a) (IBIT3, IBIT2, IBIT1) = (0, 0, 0): MSB first, Right-Justified mode, 16-bit data
b) (IBIT3, IBIT2, IBIT1) = (0, 0, 1): MSB first, Right-Justified mode, 18-bit data
c) (IBIT3, IBIT2, IBIT1) = (0, 1, 0): MSB first, Right-Justified mode, 20-bit data
d) (IBIT3, IBIT2, IBIT1) = (0, 1, 1): MSB first, Right-Justified mode, 24-bit data
e) (IBIT3, IBIT2, IBIT1) = (1, 0, 0): IIS-compatible, 24 bits max
Note 3: In either mode, sections where “SDI” is omitted are don’t care (no internal data loading).
