ADSP-21489 Self Nesting Interrupt Handling

Dear All,

I am trying to use SPORT0 to SPORT7 of ADSP-21489 in my application and wanted to enable interrupts for all SPORT channels. 

SPORT0 is part of DAI and DAI can generate only two interrupts to the Core (DAI_H and DAI_L) whereas in my application it is possible that SPORT-0 to 7 can raise interrupt while one of the ISR of SPORT is in progress.... to respond for this kind of situation I understood that feature of SelfNesting of interrupt (DAI) is required, please correct me if I am wrong. 

In  Cross Core Embedded how to enable the SelfNesting of interrupts to run ISRs written for SPORT0 to SPORT7.

Regards,

Muni.
