1 If IRQx and FI inputs meet tIFS and tIFH setup/hold requirements, they will be recognized during the current clock cycle; otherwise the signals will be recognized on the
following cycle. (Refer to “Interrupt Controller Operation” in the Program Control chapter of the ADSP-218x DSP Hardware Reference for further information on
interrupt servicing.)
2 Edge-sensitive interrupts require pulse widths greater than 10 ns; level-sensitive interrupts must be held low until serviced.
3 IRQx = IRQ0, IRQ1, IRQ2, IRQL0, IRQL1, IRQLE.
4 PFx = PF0, PF1, PF2, PF3, PF4, PF5, PF6, PF7.
5 Flag Outputs = PFx, FL0, FL1, FL2, FO.
