Figure 19. Timing Diagram for FS in the Continuous Transfer Mode
In cascade mode, the DSP should be in slave mode, i.e., it receives all frame-sync pulses from the master
though the master's FS. The master's FSD is output to the first slave and the first slave's FSD is output to the
second slave device and so on. Figure 20 shows the cascade of four TLV320AIC2xs in which the closest one to
DSP is the master and the rest are slaves. The FSD output of each device is input to the FS terminal of the
succeeding device. Figure 21 shows the FSD timing sequence in the cascade.
