ASAHI KASEI
The audio serial interface format becomes the TDM I/F format if TDM bit is set to “1”. In the TDM mode, the serial data
of all DAC (six channels) is input to the SDTI1 pin. The input data to SDTI2-3 pins is ignored. BICK should be fixed to
256fs. In the slave mode, “H” time and “L” time of LRCK should be 1/256fs at least. In the master mode, “H” time (“L”
time at I
used in double speed mode.
