Note 40. 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”.
