Op2Sel #86

Closed mw92 closed 10 years ago

mw92 commented 10 years ago

Why is the a set to zero option on Op2Sel mux? If it needs to be here, it is missing from datapath diagram.

It is needed for memory load based instructions (LDW, POP, LDF, RETI).

I have opened an issue for all things that need to be updated on the datapath diagram (#87). Cheers for spotting this one.
