^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 2)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) The codec is controlled through an I2C interface. It also has two other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) signals that can be wired up to GPIOs: reset (strongly recommended), and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) powerdown (optional).
