■ Audio Serial Interface Format
(1) Stereo Mode
When TDM1-0 bits = “00”, ten modes can be selected by the DIF2-0 bits as shown in Table 11. In all modes the serial data
is MSB-first, 2’s compliment format. The data SDTO1-2 is clocked out on the falling edge of BICK and the SDTI1-6 is
latched on the rising edge of BICK.
Mode3/4/8/9/13/14/18/19/23/24/28/29/33/34/38/39 in SDTI input formats can be used for 16-20bit data by zeroing the
unused LSBs.

Note. TVDD1 which is the Power of I/O buffer should be kept in the range of 1.6V~3.6V at Normal Speed Mode in Stereo
Mode. TVDD1 should be kept in the range of 3.0V~3.6V at Double Speed Mode and Quad Speed Mode.
