n Audio Serial Interface
The audio serial interface is used to input audio data and consists of six pins: Bit Clock (BICK), Word Clock (LRCK) &
four Data pins (SDTI 1-4). LRCK indicates the particular channel, left or right. The DIF 2-0 pins in synchronous mode
and control registers in asynchronous mode select the particular input mode. In asynchronous mode, DIF2-0 bits are
logically ORed with DIF2-0 pins. Audio data format supports 16-24 bits, right justified and left justified modes. The I
2S
mode is also supported. The AK4101A can be configured in master and slave modes.
