Control signal lines are one of the 3 lines(Address lines, data lines & CS lines) of the System bus. The Addr. lines are unidirectional whereas Data lines are bidirectional. I have a doubt with the CS lines. They carry control signals from the processor to the peripherals. Are they unidirectional or bidirectional?

"The CPU transmits a variety of control signals to components and devices to transmit control signals to the CPU using the control bus. One of the main objectives of a bus is to minimize the lines that are needed for communication. An individual bus permits communication between devices using one data channel. The control bus is bidirectional and assists the CPU in synchronizing control signals to internal devices and external components. It is comprised of interrupt lines, byte enable lines, read/write signals and status lines."

hence bidirectional
