I want to be able to feed a single 8 bus into my 1 byte memory chip, however the problem arises that I can't actually merge 8 individual 1-bit input pins into a single 8-bus input. I tried using an 8 bus input in my 1 byte memory chip to begin with, but I don't know how to separate the bus lines so that each input of the bus goes to the corresponding registry inside the 1 byte input chip.

How do I use the 8-I/O pins?
