Selected subsystems within a portable electronic device (10) are identified. Functional interdependencies between the selected subsystems are identified and recorded in a database (30) internal to the electronic device (10). Upon receipt of a change command to either change the state of any of the selected subsystems or to change the processor bandwidth (32) or clock rate, the database (30) containing the functional interdependencies is consulted for indication as to whether the commanded change will adversely affect the intended operation of any of the selected subsystems. If such an adverse affect will occur, the commanded change will be ignored, modified or delayed. |
