■ TDM Cascade Mode
(1)TDM256mode
Two devices can be connected in cascades at the TDM256 mode. In Figure 22, the SDTO1 pin of device #1 is connected
with the TDMI pin of device #2. It is possible to output 8channel TDM data from the SDTO1 pin of device # 2 as shown
in Figure 17 and Figure 20.

(2)TDM512mode
Four or less devices can be connected in cascades at the TDM512 mode. In Figure 23, the SDTO1 pin of device #1-3 is
connected with the TDMI pin of device #2-4. It is possible to output 16 channel TDM data from the SDTO1 pin of device
#4 as shown in Figure 18 and Figure 21.
