ABSTRACT:
Data processing units (14) within an integrated circuit (10) are connected by a common bus (16). Each data processing unit follows a predetermined protocol for communicating to other data processing units via the common bus (16). Further, predetermined control and/or data processing signals within the common bus (16) are multi-tasked (i.e. function multiplexed) for a normal and special modes of operation. A state machine (21) within each data processing unit (12) controls a clock circuit (23). The state machine (21) has a predetermined state diagram for controlling clock signals associated with the predetermined modes of operation.
