^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) There are no software configuration options for this device, indeed, the only
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) host connection is the I2S interface. Apart from requirements on clock
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) frequency (460 kHz to 3.379 MHz according to the data sheet) there must be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) 64 clock cycles in each stereo output frame; 24 of the 32 available bits
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) contain audio data. A hardware pin determines if the device outputs data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) on the left or right channel of the I2S frame.
