Blank as in set to 0? My sequence is pretty much this; set bits to first mux set bits to second mux turn on one anode driver wait for 3ms turn off anode driver blanking period of 200us repeat this n-times
I don't really touch muxes' bits when I am not displaying anything (nixies turned off). I only set them again when I want to display time again.
