Abstract
A device that includes: a first bus, connected between a first logic and a first circuit; a group of second buses connected between the first logic and between multiple non-high impedance circuit access logics associated with multiple circuits; wherein each circuit access logic is adapted to: (i) provide to the first logic, a circuit write value during a circuit writing period and during an idle period that follows the circuit writing period and ends when another circuit is allowed to write; and (ii) provide a default value when another circuit is allowed to write; and wherein the first logic is adapted to alter a state of the first bus in response to a change between two consecutive circuit write values.
