Table 3. Mode Setting
Audio Serial Interface Format
Three modes are supported and selected by the CKS3-0 pins as shown in Table 3 and Table 4. In all modes the serial data
format is MSB first, 2’s complement. The SDTO is clocked out on the falling edge of BCLK and the SDTI is latched on
the rising edge. The audio interface supports both master and slave modes. In slave mode, BCLK and LRCK are input. In
master mode, BCLK and LRCK are output with the BCLK frequency fixed to 64fs and the LRCK frequency fixed to 1fs.
Also audio interface format is fixed to I
2
S mode.
