5-3. Input/ Output Interface Format
The AK4601 has three digital input ports (SDIN1~SDIN3) and three digital output ports (SDOUT1~
SDOUT3). The input data format is determined by a combination of DISLx[1:0], DIEDGENx, DILSBEx
and DIDLx[1:0] bits settings (x=1~3). The output data format is determined by a of DOSLx[1:0],
DOEDGENx, DOLSBEx and DODLx[1:0] bits settings (x=1~3).
DISLx[1:0] bits / DOSLx[1:0] bits (x=1~3) control input/output data slot length.

Table 27. Data Transmission Start Timing of The Data After Second Channel
If the data transmitting timing is set to Slot length basis, the next channel’s data is transmitted
immediately without waiting a LRCK edge after transmitted one slot data (Figure 29 ~ Figure 32).
If the data transmitting timing is set to LRCK edge basis, the next channel’s data will not be transmitted
until a LRCK edge even finished transmitting one slot data (Figure 26 ~ Figure 28).
