It connects to an onboard audio codec on the |product-cb| carrier board, controlled over the ``lpi2c5`` I2C bus at address ``0x18``. For detailed hardware-level information, refer to the *7.8 SAI* chapter in the |hw-manual-link|. Usage ----- The pre-built |release-name| sample application includes the |http-link-intf-audio-selcall| module, which runs automatically at boot and drives the onboard audio codec over ``sai1``. .. include:: ../../common/support-disclaimer-us.rst
