Note 49. BICK more than setting bit must be input to each channel. In the LRCK column, “H/L” indicates
that L channel data can be input when LRCK is “H” and R channel data can be input when LRCK
is “L”. “L/H” indicates L channel data can be input when LRCK is “L” and R channel data can be
input when LRCK is “H”.
Note 50. The default settings in Register Control Mode are shown below.
TDM1 bit = “0”, TDM0 bit = “0”, DIF2 bit = “1”, DIF1 bit = “1”, DIF0 bit = “0”
