Audio Interface Format
Two kinds of data formats can be chosen with the DIF bit (Table 4). In both modes, the serial data is in MSB first, 2’s
compliment format. The SDTO is clocked out on the falling edge of BICK. The audio interface supports both master and
slave modes. In master mode, BICK and LRCK are output with the BICK frequency fixed to 64fs and the LRCK
frequency fixed to 1fs.
