In ADSP-SC59x/2159x processors, all source signals from Group A/B/C/D/E/F on one DAI are automatically included as source signals to the corresponding default groups A/B/C/D/E/F. With this setup, signals from one part can be sent to the other part between DAI0 and DAI1. Therefore, there is no cross connection is required in ADSP-SC59x/ADSP-2159x processors.
For instance:
SRU(SPT0_AD0_O, SRC7_DAT_IP_I);
In this example, SPT0_AD0_O originates from DAI0, while SRC7_DAT_IP_I belong to the DAI1 group.
