my problem comes from multisim
it is necessary to be able to replace NADS by a pulse generator I think that at the end of the cycle NADS returns a signal hight or low that makes change of state the toggle we have the good schemat slow step halt run
have approached the final schemat I will check the schemat PROTECT LOAD
have approached the final schemat I will check the schemat PROTECT LOAD
we are almost at the end also remains the layout of the latches and I think that to reduce the current in the drivers we could use a serial LED on the common LED
halt is a break with D7 I don’t understand the whole explanation
