Suppose we are using 120 nanosecond ROMs, which have valid data on the bus 120 ns after the falling edge on the Output Enable line (with a clock rate of 25 MHz (which means a clock cycle of 40 nanoseconds). How many wait states must the microprocessor insert into each bus cycle that reads from the ROM?
