For the ADSP-SC59x/ADSP-2159x set of processors, the SRU macro can be used to connect the source and destination signals of DAI0, DAI1, and between DAIs (DRU). The SRU2 macro is also defined and is identical to SRU. The SRU2 macro is provided to maintain compatibility with the previous versions of SRU header support that configured DAI0 using SRU and DAI1 using SRU2.
An example use of SRU is:
SRU (DAI0_PB12_O, SPT0_ACLK_I) for DAI0
SRU (DAI1_PB10_O, SPT4_ACLK_I) for DAI1
SRU (PCG0_CLKA_O, SPT7_ACLK_I) for DAI0-DAI1
SRU (PCG0_CLKC_O, SPT1_ACLK_I) for DAI1-DAI0.
