FLAG pin interrupt & "interrupts()" function availability in SC584

I am porting a piece code which was written for ADSP-21489 to new processor ADSP-SC584. I have some questions regarding it.

1.) I researched regarding the FLAG pins (interrupt pins IRQ 2-0) which used to be present on 21489 as dedicated pins. However, I don't see any such dedicated interrupt enabled pin functionality on SC584. These functionality has been removed from SC584. Am I right about this?

2.) The old ADSP-21489 used to support "interrupts()" function in program, which used to perform faster interrupt context switching. This "interrupts()" fast interrupt is also not available in the newer ADSP-SC584. Am I right? If I am wrong, where can I read more about it? Or see some example regarding it?

Thanks
