NOTES
1IRQx=IRQ0, IRQ1, and IRQ2.
2If IRQx and FI inputs meet t
IFS 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.
