  • Page 22: Separate Operation Modes

    EVM Operation Modes 3.1 EVM Operation Modes TLV320AIC10/11 devices have two operation modes, master or slave. The device is a master device if it generates the shift clock (SCLK) and frame sync signal (FS) and sends them to slave devices. A slave device uses external SCLK and FS signals.

  • Page 23: Aic10/11 Slave Mode

    Other Basic Configurations AIC10/11 onboard device U1 works as a master to McBSP0 (and/or to other AIC10/11 devices) when the M/S pin is set to high. Device U2 works as a mas- ter to McBSP1, not only when the M/S pin is set to high, but also when jumpers W13, W15, W16, and W17 are configured to position 1–2.
