DAI and DPI pins configuration for multiple SPORT and PCG

have to use all ADSP-21489 SPORT channels in a system with synchronous sampling in ADCs and DACs.

DAI pins have to be used for SPORT data lines and external master clock input to PGG, but PCG C and D outputs (FS and BCLK) may be routed to DPI pins, so may I have FS and BCLK for all SPORT ports and channels on DPI pins ?

As I see, SPORT clock generators cannot use external clock as source, so must use PCG.


Kind regards
