I want to do a logic AND between an audio input and a logic DC value say 0x3, and use that output to feed the index selectable multiplexer as the selector, will it work? The SigmaStudio manual says the logic operations expect DC inputs, like 0 and 1, and for the instance of logic AND, it only compares whether two inputs are same or not. Another issue is index selectable mux only takes 28.0 format, I guess it won't work if I connect it with a logic AND which has 5.23 output. Anyway, how do I approach this kind of problem, i.e. only taking some LSBs from the signal and use it as a selector? Thanks.
