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 User’s Manual for further information on interrupt servicing.)

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