Abstract
Digitally controllable ICs or function blocks in an electronic apparatus are connected through control bus lines, and a switch device is provided for disconnecting one of the digitally controllable ICs or function blocks from the control bus so that the control bus is not disabled when that one IC is turned off or is not occupied when the IC is operating in its internal processing mode. Therefore, communication between the remaining ICs can be maintained through the control bus.
