ADVANCE INFORMATION
The TDM mode reduces the number of DOUT pins in the application by packing channel data into the DOUT pins. TDM mode is engaged automatically when the programmed number of DOUT pins is less than the number of ADC channels. The DP_TDM[1:0] bits of the DP_CFG1 register program the number of DOUT pins. When programmed, any inactive DOUT pins automatically change function to DIN pins for daisy-chain support.
Figure 7-32 though Figure 7-34 provide three levels of TDM operation. When channels are powered down, the slot position is retained.
