ABSTRACT:
An enable propagation controller employed in an integrated circuit operates in either a sequence manager mode or a transparent mode. When operating in the sequence manager mode, the enable propagation controller allows a set of signals intended to enable either a set of transmission or a set of reception signals to pass through to their corresponding transmission or receptions sub-circuits. Each of the signals in the desired set is allowed to pass through in a predetermined sequence and for a predetermined duration that may or may not be influenced by a set of control bits received by the enable propagation controller. When operating in a transparent mode, all enable signals are allowed to pass through to corresponding intended sub-circuits.
