NOTES

1IRQx=IRQ0, IRQ1, and IRQ2.

2If IRQx and FI inputs meet tIFS and tIFH setup/hold requirements, they will be recognized during the current clock cycle; otherwise they will be recognized during the

following cycle. (Refer to the “Interrupt Controller” section in Chapter 3, Program Control, of the ADSP-2100 Family User’s Manual for further information on

interrupt servicing.)

3Edge-sensitive interrupts require pulse widths greater than 10 ns. Level-sensitive interrupts must be held low until serviced.
