■ Cascade TDM Mode
(1) TDM256 mode
The AK5397 supports cascading of up to four devices in a daisy chain configuration at TDM256 mode. In
this mode, the SDTO1 pin (SDTO2 pin) is connected to the TDMIN1 pin (TDMIN2 pin) of next device.
When four devices are connected by daisy-chaining as Figure 29, the SDTO1 pin (SDTO2 pin) of device
#4 can send 8ch TDM data.
