Invention relates to an architecture of a message bus. This apparatus and method of operating a message bus is used in digital systems for reducing the number of additional signals lines and comprises a first set of lines contained in the message bus to send control signals and to send data bits between the modules in the second duration. Because of the use of same signal line for multiple purposes, the aggregate number of physical lines required in the message bus are reduced.
