Note that SDATAOUT and SDATAIN data is delayed one BITCLK because AC’97 controller causes
SYNC signal high at a rising edge of BITCLK which initiates a frame.
“Output” stream means the direction from AC’97 controller to the AK4651, and “Input” stream means the direction from
the AK4651 to AC’97 controller.

Figure 34. AC-Link protocol
AC-link protocol identifies 13 slots of data per frame. The frequency of SYNC is fixed to 48kHz. Only Slot 0, which is the
Tag phase, is 16bits, all other slots are 20bits in length. These slots are explained in later sections.
