- Clock: 1000 Hz
How it works
On write enable, the four data-inputs are saved to the d-flipflops selected by the address inputs. The output is always read from the current selected flipflops.
How to test
Connect a clock, buttons for reset and write_enable and switches for address and data like shown below. The output can be read by using 4 LEDs or any other kind of binary output device.
