If IRQx and FI inputs meet t
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 pulse widths greater than 10 ns; level-sensitive interrupts must be held low until serviced.
IRQx = IRQ0, IRQ1, and IRQ2.
Flag Output = FL0, FL1, FL2, and FO.
IRQx or FI Setup before CLKOUT Low
