If
IRQx
and FI inputs meet t
and t
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-2100 Family User’s Manual
for further information on
interrupt servicing.)

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