You can do it in one fewer clock cycle per loop by just using the register instead of the extra scratch memory space :) (I also reset the loop at the end or it would be two fewer): RAM AD PC ADDR ________ _ _ ---- |---*****|-|*| ; OUTPUT the register ---* |-*-*-*--|-|-| ; IF MAX, goto LBL_RESET --*- |--*--**-|-|-| ; else add ONE to the register... --** |-*------|-|-| ; ...and start over. -*-- |-----***|-|-| ; LBL RESET: read in ZERO to the register... -*-* |-*------|-|-| ; ...and start over. -**- |-------*|-|-| ; ONE (r/o data) -*** |--------|-|-| ; ZERO (r/o data)
