the project states that only one program may use the data bus at one time, but doesn't clarify what actions equate to a use of the bus. do all calls to a device require the bus (but not RAM, so a program can be executing on the CPU while one and only one device is working)? also, dose loading a command into the CPU require "accessing RAM", and therefor also require the data bus?
