The AK4101A is a four outputs digital audio transmitter (DIT) which supports data rate up to 192kHz
sample rate operation. The AK4101A supports AES3, IEC60958, S/PDIF & EIAJ CP1201 interface
standards. The AK4101A accepts audio data and auxiliary information data and etc, which is then
biphase-encoded and driven on to a cable. The audio serial port supports eight formats.

... Asynchronous Mode/ Synchronous Mode 1. Asynchronous Mode (software controlled) The AK4101A can be configured in the asynchronous mode by connecting the ANS pin to logic “L”. In this mode the 16 to 24-bit audio samples are accepted through a configured audio serial port, and the channel status and user data through a serial control host interface (SCI) ...

... In audio routing mode, the FS0/CSN pin changes definition to AKMODE pin. When set “H” the AK4101A can be configured directly with the AK4112B receiver. When set “L”, it may be used with other non- AKM receivers. Setting the part with TRANS pin = “1” and ANS pin = “0” is illegal and places the chip into a test mode ...

... AK4101A. Figure 19 illustrates the serial data flow associated with SCI read and write operations. C1-0 bits are the chip address. The AK4101A looks for C1-0 bits “11” before responding to the incoming data. R/W is the Read/Write bit which is “0” for a read operation and “1” for a write operation. The register address contained in A7-0 bits is decoded to select a particular byte of the control register ...
