SAI Predefined Configurations
Synchronous Audio Interface (SOMRT1061)

I2S Slave Mode Configurations

These configurations set up the SAI as an I2S slave (receives clock from external master). Configurations are available for 8, 16, and 24-bit word widths, with various clock routing:

  • _RK: Uses receive clock (BCLK from RX pins)
  • _TK: Uses transmit clock (BCLK from TX pins)
  • _TKRK: TX uses TX clock, RX uses RX clock (independent clocks)

Left-Justified Slave Mode Configurations

These configurations set up the SAI for left-justified audio format (data starts immediately with frame sync, no delay). Available in 8, 16, and 24-bit variants.
