Fore types of data format are available and are selected by setting the M/S, TDM1-0, DIF1-0 bits (Table 14, Table 15,
Table 16). In all modes, the serial data is MSB first, 2’s complement format. Audio interface formats can be used in both
master and slave modes. The SDTO is clocked out on the falling edge (“↓”) of BCLK except DSP mode.
In TDM128 mode at master operation, BCLK becomes 128fs independent of select the BCLK1-0 bits.
In TDM256 mode at master operation, BCLK becomes 256fs independent of select the BCLK1-0 bits.
TDM mode dose not correspond the PLL Slave Mode2.
Belows are minimam voltage of DVDD at the audio interface respectivity.
Note. In TDM mode at master operation, LRCK can be output by writing “0101” at TE3-0 bits and “1” at TMASTER bit.
